Answer:
![\large\boxed{S.A.=4500\pi\ in^2\approx14130\ in^2}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BS.A.%3D4500%5Cpi%5C%20in%5E2%5Capprox14130%5C%20in%5E2%7D)
Step-by-step explanation:
The formula of a surface area of a ball (sphere):
![S.A.=\dfrac{4}{3}\pi R^3](https://tex.z-dn.net/?f=S.A.%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20R%5E3)
R - radius
We have R = 15in. Substitute:
![S.A.=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3375)=4500\pi\ in^2](https://tex.z-dn.net/?f=S.A.%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%2815%5E3%29%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%283375%29%3D4500%5Cpi%5C%20in%5E2)
If you want to get an approximation, then:
![\pi\approx3.14\\\\S.A.\approx(4500)(3.14)=14130\ in^2](https://tex.z-dn.net/?f=%5Cpi%5Capprox3.14%5C%5C%5C%5CS.A.%5Capprox%284500%29%283.14%29%3D14130%5C%20in%5E2)
