(a) 28π cm

(b) 88 cm

Step-by-step explanation:

Part A — Give an exact answer in terms of π.

To find circumference of a circle, our formula is:

Where:

Radius is,the line segment or value from center to one of endpoints. Our radius is given as 14 cm in the shown attachment.

Henceforth, our circumference is:

So for part A, the circumference is 28π cm.

Part B — Use π ≈ 22/7 and express your answer as a fraction in lowest terms.

For this part, use the circumference that we solved from part A:

Substitute π = 22/7 in.

Henceforth, the circumference in Part B is approximately 88 cm.
