How to measure the diameter of a lampshade?

To find out what width is right for your shadow, **measure** Multiply your lamp base by two. For round bases, **measure** pass directly through; **measure** The diagonal is a square base. The widest part of your shade should be at least half an inch wider than the widest part of the base on each side.

What is the definition of the diameter of a circle?

In geometry, a **diameter of circle** is any straight line segment through the center **circle** and its endpoint is at **circle**. It can also be defined as the longest chord **circle**.

## How to measure the diameter of a circle?

The radius is the distance from the center **circle** to its edge.For example, if the radius **circle** is 4 cm, then **diameter** of **circle** 4cm x 2 or 8cm.if you know the circumference **circle**, divided by π to get **diameter**.

## What is the diameter of the cylinder?

This **diameter**, or the distance across a **cylinder** through the center **cylinder** is 2R (twice the radius).surface area of open end **cylinder** (as shown) is 2 RL.if **cylinder** The ends are covered with a surface area of 2 RL + 2 R. 2. Volume of a **cylinder** is R2L.

## What is the diameter of a rectangle?

One **Rectangle** Is any flat shape with four straight sides and four 90-degree or right angles.each side **Rectangle** Connect with two right angles.This **the diameter of a rectangle** is the length of the diagonal, or either of the two long lines connecting the diagonals.

## What is the formula to calculate diameter from perimeter?

solve **equation** for **diameter** Round, d = C/π. In this example, “d = 12 / 3.14”.or **diameter** Equals twelve divided by 3.14. “divide by **circumference** Get the answer via pi. under these circumstances, **diameter** would be 3.82 inches.

## What is the definition of the diameter of a circle?

In geometry, a **diameter of circle** is any straight line segment through the center **circle** and its endpoint is at **circle**. It can also be defined as the longest chord **circle**.

## How do you measure the size of a circle?

Circumference = π x Diameter **circle** (Pi times diameter **circle**).Just divide the circumference by π and you will get **length** diameter of.The diameter is the radius times two, so divide the diameter by two and you will get the radius **circle**!

## What is the formula for the diameter of a circle?

perimeter of a **circle** It is equal to pi times the diameter.The diameter is twice the radius, so the equation for the circumference of a circle **circle** Use a radius that is twice the radius.

## How do you find the diameter and circumference of a circle?

**Look for** This **diameter** a circle **circumference** 21.98 feet.To solve this problem, we need our formula to find **circumference** a circle. C = πd Next, we fill in the given information. 21.98 = (3.14)d To solve this, we need to figure out how many multiples of 3.14 will give us 21.98.

## Is the radius of a circle half the diameter?

This **radius** The length of this circle is 7 inches, so **diameter** is 2(7) = 14 inches.This **radius** Yes **half** This **diameter**, or.This **diameter** The length of the circle is 36 feet, so **radius** is the foot. The distance around a circle is called the perimeter.

## What is the diameter of the circle?

**radius**, **diameter** and perimeter.This **radius** is the distance from the center outward.This **diameter** Go straight through the circle, through the center. A circumference is the distance around a circle.

## How can I find the diameter of a circle if I know the area?

**For example, our area is 303,000 square meters.**

- Divide the area (in squares) by Pi (about 3.14159). Example: 303,000/3.14159 = 96447.98.
- Take the square root of the result (example: 310.56). This is the radius.
- Now double the radius to get the diameter (eg: 621.12 meters).

## How can you find the circumference of a circle?

**How to find the circumference of a circle:**

- The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
- If a circle has a diameter of 4, then its circumference is 3.14*4=12.56.
- If you know the radius, the diameter is twice as large.

## What is the radius of the circle?

perimeter is the outer perimeter of a **circle**. This is a surrounding distance **circle**. One **radius** Can be a straight line from any point on the circumference to the center of the circle **circle**. if you put two **radius** together, edge to edge, through the center **circle**, you will get a diameter.

## How do you calculate the circumference of a circle?

Substitute numbers to solve C. Now we know that 2πr = C. Go back to the original math problem and see what r (radius) equals. Then replace π with 3.14, or use the calculator’s π button for a more accurate answer. Multiply 2πr using these numbers.the answer you got is **circumference**.

## Where is the circumference of the circle?

a surrounding distance **circle** On the other hand is called **circumference** (C).Half the diameter, or the distance from the midpoint to the midpoint **circle** the boundary, called the radius **circle** (r).

## How to calculate the diameter of a ball?

**measure** fitness perimeter **ball**. healthy **ball** Dimensions are listed in **diameter** (the straight line distance from one side of the sphere to the other, through the center), not the circumference.Divide the circumference by pi or 3.14 to get **diameter**.

## How to calculate the area of a circle?

to find **area** One **circle** with the radius, square the radius, or multiply it by itself.Then, multiply the squared radius by pi, which is 3.14, to get **area**. to find **area** With the diameter, just divide the diameter by 2, plug it into the radius formula, and solve as before.

## What are round chords?

One **round chord** is a straight line segment whose endpoints are at **circle**. A secant, or just a secant, is an infinite extension of a line **string**. More generally, a **string** is a line segment connecting two points on an arbitrary curve, such as an ellipse.the word **string** From Latin chorda, meaning bowstring.

## How do you find the diameter of a sphere?

**method one** **Use the radius calculation formula**

- If you know the diameter, find the radius. The radius is half the diameter, so use the formula r = D/2.
- If you know the perimeter, find the radius. Use the formula C/2π.
- If you know the volume of the sphere, calculate the radius.
- Find the radius from the surface area.
