Answer:
Step-by-step 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
