Question

The circumference is 25 pi What is the diameter?​

Answer 1

Diameter = 25

Explanation:

The circumference of a circle is 25 pi

Circumference of a circle is given by,

C = 2πr

25π = 2πr

Dividing both sides by 2π

`(25\pi)/(2\pi)=(2\pi r)/(2\pi)\\\\12.5 = r\\`

Diameter = 2r

Diameter = 2(12.5)

Diameter = 25

Answer 2

d=25

Explanation:

d=C/Pi

d=25pi/pi

d=25
