What is the circumference (in inches) of a circle with radius of 5 inches? Use 3.14 for n. A. 31.4 in
B. 15.7 in

A. 31.4 in.

Step-by-step explanation:

Formula for the circumference:

C = dπ (d = 2r)

Therefore:

C = 10π

C = 10 · 3.14

C = 31.4 in.

A: 31.4 in

Step-by-step explanation:

Use the equation C = 2πr to solve your problem.

Since you are given the radius r you only need to plug in 5 in. to r and calculate it on the calc. When you multiply everything together you should get 31.4 in.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
