Answer:

b. 20πcm

Step-by-step explanation:

The circumference is given by

C = 2*pi*r

   = 2* pi *10

    = 20pi

Wolfyy

Circumference Formula: C = 2πr

C = 2π(10)

C = 20π

The correct answer is b. 20πcm

Note that if you want to solve for the exact circumference, you don't want to solve for pi since its a non-terminating decimal. If you want to round the nearest circumference multiply pi with 3.14.

Best of Luck!
