Question

What is the circumference of a circle (to the nearest whole number) whose diameter is 12? a. 38 b. 12 c. 113 d. 19

Answer 1

The answer would be ≈37.7 or to the nearest whole number, 38

Explanation:

C=πd is used to find the circumference of the circle

When you plug in 12, you get this equation:

C=π·12

Which then roughly equals ≈ 37.69911, or 38.
