Question

Find the exact circumference of the circle shown.
a. 32pi b. 16pi c. 256pi d. 64pi



Answer 1

The circumference is 64$\pi$


Work

C = 2$\pi$r
C = 2 * $\pi$ * 32
C = 64$\pi$

Answer 2

Answer:

32π which is equal to 100.53

Step-by-step explanation:

The measurement given in the sketch, refers to the diameter of the circle, not the radius. The formula for the circumference of a circle uses the radius.

The radius,which is half of the diameter, is 16.

Using the formula for circumference:

C = 2πr

C = 2π(16)

C = 32π

C = 100.53
