Question

A clock is shaped like a circle with the diameter of 14in. To the nearest inch, what is the circumference of a clock?

A. 88 in
B. 44 in
C. 22 in
D. 28 in

Answer 1

B. 44 in

It’s the diameter times pi. So multiply 14 inches with 3.14 and round the decimal

Answer 2

The circumference is 44in

Explanation:

There is an equation that relates the diameter with the circumference of a circle:

Diameter(D)= (Circumference(C))/π

Where π is pi number, which is a constant number, and is equal to 3,1416

In order to know what is the circumference, you have:

D=C/π

Then:

C=D*π

C=14 in*3,1416

C=43,98

C= 44 (round number)
