Question

Find the circumference of a circle with a radius of 4 feet

Answer 1

Hii.

Explanation:

The circumference of a circle with a 4-foot radius is about 25.13 feet. (C = r x 2 x Pi)

Answer 2

Explanation: If we are finding the circumference of a circle, we're finding the distance around the circle. To find the circumference of a circle, we use a formula which is as followed.

`C = 2\pi r` which means 2x the radius.

We can also represent this as followed.

`C = D\pi` which means we will take our diameter which is 8 because if we multiply our radius which is 4 by 2, we get 8.

Therefore, our circumference is going to equal the diameter which ends up being 8 feet multiplied by pi.

Circumference =
`8\pi feet`.
