suppose a sphere has a volume of 3,000 cm3. Find the surface area
\(\dfrac{4\pi r^3}{3}=3000\\ 4\pi r^3 = 9000\\ \pi r^3 = 2250 \\r=\sqrt[3]{\dfrac{2250}{\pi}}\)
r is the radius of the sphere.
\(\text{Surface area}\\ =4 \pi r^2\\ = 4(\dfrac{2250}{\pi})^{\frac{2}{3}}\\ \approx 320.195399866\;\;\text{cm}^2\)
