Answer:
Area= 19.63 units squared Circumference= 15.71 units
Step-by-step explanation:
Area= π r ^2
Circumference= 2π r
540
540= 18% of 97.2
5 is the answer
-10 + 5 = -5
![4 \pi ^{2} r ^{3} = T^{2}GM \\ r^{3} = \frac{T ^{2} GM}{4 \pi^{2} } \\ r = \sqrt[3]{ \frac{T ^{2}GM }{4 \pi ^{2} } }](https://tex.z-dn.net/?f=4%20%5Cpi%20%5E%7B2%7D%20r%20%5E%7B3%7D%20%3D%20T%5E%7B2%7DGM%20%5C%5C%20r%5E%7B3%7D%20%20%3D%20%5Cfrac%7BT%20%5E%7B2%7D%20GM%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D%20%20%5C%5C%20r%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7BT%20%5E%7B2%7DGM%20%7D%7B4%20%5Cpi%20%20%5E%7B2%7D%20%7D%20%7D%20%20)
