Question

What is the approximate circumference of a circle that has a diameter of 25 yards? (Use 3.14 for pi ). C = a0 yd

Answer 1

`\huge\boxed{C=25\pi\ yd\approx78.5\ yd}`

Explanation:

The formula of a circumference of a circle:

`C=d\pi`

d - diameter

We have d = 25yd.

Substitute:

`C=25\pi\ yd`

Use
`\pi\approx3.14`:

`C\approx(25)(3.14)=78.5\ yd`

Answer 2

78.5 yds

Explanation:

The circumference is given by

C = pi *d

C = 3.14 * 25

C =78.5
