Question

The formula for the circumference of a circle is C= 2pir where r is the radius and c is feb circumference. The equation solved force is r=C/2pi

Find the radius of a circle that has a circumference of 16pi.
A. r=4
B. r= 8
C. r=12
D. r= 16

Answer 1

Answer: B

Explanation:

Answer 2

choice B is correct.

Explanation:

The formula for r is given in the question statement,

r= C/π where C is the circumference.

If C= 16π

r=16π/2π

r= 8

then the radius of the circle that has circumference 16π is 8 which is answer.
