Students learn that the

**circumference**of a**circle**is the distance around the**circle**, and the formula for the**circumference**of a**circle**is 2 times pi times the radius of the**circle**. Pi is the ratio of the**circumference**to the radius, which is approximately 22/7 or 3.14.Keeping this in consideration, what is the circumference of a 5 ft diameter circle?

Assuming the **circle diameter** is equal to **5 ft**, then the **circle circumference** is equal to pi×**diameter** or 3.14159×**5 ft** = 15.70795 **ft** or approximately 15.7 **ft**.

Also Know, what is the circumference of 4? 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**, its **circumference** is 3.14***4**=12.56.

In this manner, what is the circumference of a 4 ft diameter?

3.14 x **4** = 12.56 **ft**.

What is the circumference of a 3 foot diameter circle?

If the radius of your **circle** is **3 feet**, for example, its **diameter** is **3** × 2 = 6 **feet**; and the **circumference** is then 6 × 3.14 = 18.84 **feet**, or 6 × 3.1415 = 18.849 **feet** if you're asked for a more exact answer.
