(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.

d≈7.07in

step-by-step explanation:

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
