inches. Round your answer to the nearest ten-thousandths.
Please help :(

Answer 1

31.42

Explanation:

you will need a calculator for this

you will need to do 2 x pi x r = C

2 x 3.14 x 5

2x5=10

3.14 x 10 = 31.42

you get 2 when you round to the nearest ten-thousandths

pi = 3.14159

Answer 2

• 31.4159 in

Explanation:

Formula for circumference

• C = 2πr, where r is radius

Solving for the circle with radius of 5 in

• C = 2*π*5 = 10π = 31.4159265359 ≈ 31.4159 in rounded
