Answer 1

The circle's circumference is 25.13 centimeters.

Explanation:

C=2pi*r where r=radius

Since the diameter of a circle is 8 centimeters,

we know that the radius is 4 centimeters.

C=2pi*4=8pi=25.13

Answer 2

25.12 cm

Explanation:

The circumference of a circle is

C = pi * d

C = 3.14 * 8

C =25.12 cm
