153.86=3.14$$\times r ^{2}$$

anonymous · Answer

153.86/3.14=49

anonymous · Answer

Actually I just need circumference and thank you

anonymous · Answer

49=$$r$$
r=7

anonymous · Answer

So, your radius is about 7, and your diameter is 2r, so 14

anonymous · Answer

Circumference=3.14 times diameter
3.14 times 14
