Answer 1

C = 2 × pi × r
C= 2 × pi × 2.5
Your answer is
C = 5 × pi

Answer 2

The diameter passes through the circle, and the exact circumference of the circle is 15.7 inches

How to determine the exact circumference?

The diameter is given as:

d = 5 inches

The circumference is calculated using:

C = πd

So, we  have:

C = 3.14 * 5

Evaluate

C = 15.7

Hence, the exact circumference of the circle is 15.7 inches
