given a circle with a diameter of eight what is the circumference?

Answer 1

Answer: C=2pir or diameter(pi)

Step-by-step explanation:

The diameter of a circle stretches from one side to the other, the Radius (r) goes from the center to the side meaning it is twice the diameter.

To solve this just half the diameter and insert it into the first equation or just plug it in for diameter.

The answer is

D. 8pi

Answer 2

D

Explanation:

the circumference (C) of a circle is calculated as

C = πd ( d is the diameter ) , then

C = π × 8 = 8π
