Question

The volume of a sphere is 5,000pi m3. What is the surface area of the sphere to the nearest square meter?

Answer 1

surface area of a sphere = \(4\pi r^2\)

the volume of a sphere= \(\frac{4}{3} \pi r^3\)

so \[5000\pi = \frac{4}{3}\pi r^3\]

can you solve for r there ^

Answer 2

I still dont get it.

Answer 3

=> r^3 = 5000 x 3 / 4
=> r^3 = 3750
Now find the cube root this will give u value of r

Answer 4

how do you get cube root?

Answer 5

take LCM of 3750 and make triplets of factors

Answer 6

so i get 15.5... now what?
