Question

Which equation gives the value of the circumference, C, of a circle with a diameter of 56 feet?

Answer 1

`C=\pi (56)`

Explanation:

Answer 2

`C=\pi (56)`

Explanation:

we know that

The circumference of a circle is equal to

`C=\pi D`

where

D is the diameter

in this problem we have

`D=56\ ft`

substitute

`C=\pi (56)` -----> equation that give the value of the circumference

`C=56 \pi\ ft`
