Answer 1

65.9734457254 or 65.97

Explanation:

c= pi x diameter

c= pi x (10.5 x 2)

c= pi x 21

= 65.9734457254

Answer 2

66 in approx

Explanation:

Given data

Radius= 10.5 inches

The circumference is given as

C= 2πr

Substitute

C=2*3.142*10.5

C=65.982

Hence the Circumference is 66 in approx
