Question

The volume of sphere is 2254 pi m cubed. what is the surface area to nearest tenth?

Answer 1

1,783.3m^2

Explanation:

I took the test

Answer 2

`V=2254\pi\ m^3\\\\V=(4)/(3)\pi r^3\\\\\text{therefore}\\\\(4)/(3)\pi r^3=2254\pi\ \ \ |:\pi\\\\(4)/(3)r^3=2254\ \ \ |\cdot(3)/(4)\\\\r^3=1690.5\to r=\sqrt[3]{1690.5}\to r\approx11.9126\to r\approx11.9`


`S_A=4\pi r^2\to S_A=4\pi\cdot11.9^2=4\pi\cdot141.61=566.44\pi\approx1778.6\ m^2`
