Could someone help me???

Answer 1

Explanation:

Problem 2:

1) You need to know the diameter or the radius of the circle to find out the circumference.

2) Diameter is twice of the radius. 9*2= 18

3) You can subsitute 17 as r, and solve. (it's 106.76 feet)

4) C= pi * d

C= pi*10= 31.4

C= pi * 2r

C= pi* 2* 5= pi*10= 31.4
