The volume of sphere is
feet cubed.
Step-by-step explanation:
Given,
Surface area of sphere = 196π square feet
Surface area of sphere = 4πr²
We will find radius of sphere.
![4\pi r^2=196\pi](https://tex.z-dn.net/?f=4%5Cpi%20r%5E2%3D196%5Cpi)
Dividing both sides by 4π
![\frac{4\pi r^2}{4\pi}=\frac{196\pi}{4\pi}\\\\r^2=49](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Cpi%20r%5E2%7D%7B4%5Cpi%7D%3D%5Cfrac%7B196%5Cpi%7D%7B4%5Cpi%7D%5C%5C%5C%5Cr%5E2%3D49)
Taking square root on both sides
![\sqrt{r^2}=\sqrt{49}\\r=7](https://tex.z-dn.net/?f=%5Csqrt%7Br%5E2%7D%3D%5Csqrt%7B49%7D%5C%5Cr%3D7)
The radius is 7 feet.
Volume of sphere = ![\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![Volume=\frac{4}{3}\pi (7)^3\\\\Volume= \frac{4}{3}\pi *343\\\\Volume = \frac{1372}{3}\pi](https://tex.z-dn.net/?f=Volume%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%287%29%5E3%5C%5C%5C%5CVolume%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%2A343%5C%5C%5C%5CVolume%20%3D%20%5Cfrac%7B1372%7D%7B3%7D%5Cpi)
The volume of sphere is
feet cubed.
