Question

I need help please.
Second box= feet or square feet

Answer 1

To find four circumference we have to do πd as this is the law and in this scenario we are given the actual diameter which is 10 and 10π is 31.4 to 1dp.

The approximate would be 3.14 times by 10 which would make 31.4 and both my exact and approximates are close.

So the exact answer is 31.4

And approximate is 31.4

Answer 2

Answer: 2.) 31.41 feet 1.)

Explanation:

1.) Divide the diameter in half, to get the radius.

10 / 2 = 5

2.) Use the circumference of a circle equation, 2
`\pi`r.

2
`\pi`(5) ≈ 31.41 feet

3.) Remember that circumference is not in square feet, as it is the length of the perimeter of the circle, not an area.

4.) To get the exact circumference, convert 31.41 to radians.

31.41(
`\pi` / 180) = 0.548207918
