## What is the circumference of 20 diameter?

So 20 x 20 (radius squared) times pi is 1256. Circumference of a circle is diameter times pi. So 40 (2 radii means one diameter) times pi is **125.6 inches**. Hope I helped.

## What is the circumference of a 22 foot circle?

Answer: The circumference of a circle with diameter of 22 units is approximately equal to **69.08 units**.

## How do you find the area of a circular pool?

If you know the diameter or radius of the circle, you can calculate the area with the help of Pi (π). The formula is **πR ^{2}, or [3.14 x (Radius squared)]**.

## How many feet around is a 21 foot pool?

The circumference is 21π feet or **66 feet**.

## What is the radius of a 24 foot round pool?

If the diameter of the round pool is 24 ft, then its radius is **12 ft**.

## How do you find the area of a circle with a diameter of 20?

1 Answer

- ∙A=πr2←r is the radius.
- here diameter =20⇒r=202=10 in.
- ⇒A=π×102=100π≈314.2.

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

The circumference of a circle can be calculated using either of the following formulas: **C=?d or C=2?r**. We know that the diameter of the circle is 8 cm, and an approximation for pi is 3.14, so we can plug these values into the formula C=?d. The formula becomes C=(3.14)(8), which simplifies to 25.12.

## What is the circumference of a 26 foot diameter circle?

That is 26 ft divided by two. So it will be **13 ft**. Now we have to find out the circumference. The formula for circumference circumference of a circle is 25 are.

## How do you find a diameter?

How to Calculate Diameter?

- Diameter = Circumference ÷ π (when the circumference is given)
- Diameter = 2 × Radius (when the radius is given)
- Diameter = 2√[Area/π] (when the area is given)

## What is the circumference of 18 ft circle?

The answer is **56.57** .

## How do you measure an 18 foot round pool?

Size of Your Yard: Essential Above Ground Pool Buyers Guide

## How do you calculate the volume of water in a round pool?

**Length x width x average depth x 7.5** = volume (in gallons)

Measure the length, width, and average depth of the pool, rounding each measurement off to the nearest foot or percentage of one foot.

## How do you calculate the amount of water in a round pool?

Round pool: **Take the Diameter times Diameter, times the average depth, times 5.9**. For example, for an 18 ft. pool 4 ft. high you would multiply 18 x 18 = 324.

## What is the circumference of a 20 foot round pool?

So, a round pool with a 20-foot diameter has a circumference of 3.14 x 20, or **62.8 feet**.

## What is the diameter of a 14 ft pool?
