## What is the circumference of a 15 cm diameter circle?

Approximately the circumference of the circle is 47.124.

**How do you find the circumference of a radius of 15?**

How to find the circumference of a circle?

- Multiply the radius by 2 to get the diameter.
- Multiply the result by π, or 3.14 for an estimation.
- That’s it; you found the circumference of the circle.

**What is the diameter of a 15 circle?**

The diameter of the circle will be 30 inches.

### What is the circumference of a 15 ft round pool?

**How do you find the area of a 15cm square?**

Answer Expert Verified Given, Side of square = 15cm . Area of Square =( side) ² .

**How do you calculate circumference with diameter?**

Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, “C” represents the circumference of the circle, and “d” represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.

## What is the radius if the circumference is 15 Pi?

And the answer to the circumference of a circle with a radius of 15 is approximately: ≈ 94.2 We shortened Pi to two decimal points which is why the answer is just approximate.

**What is circumference divided by diameter?**

By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference of a circle is equal to pi times the diameter (c = πd).

**How do you calculate the circumference of a pipe?**

The circumference of a pipe is the distance around the pipe. In order to calculate the circumference, you need to know the diameter of the pipe. The diameter is the distance from one side of the pipe to the direct opposite side of the pipe. You also need to know pi. Pi is typically estimated as 3.14.
