Question

The radius of a circular clock is 10.5 inches.Which measurement is the closet to the measurement of the circumference of the clock in inches.

A.33

B.132

C.66

D.346

Answer 1

C: 66 in.

Explanation:

The circumference formula is C = 2(pi)(r). Here, r = 10.5 in. Thus, the circumference of the clock to the nearest inch is:

2(3.14)(10.5 in) = 65.94 in, which rounds off to C: 66 in.
