Question

The volume of a sphere is `4,000pi` `m^3`. What is the surface area of the sphere to the nearest square meters?

Answer 1

I tried this:

Explanation:

You know that the volume of the sphere is:

`V=4/3pir^3`
with yor data we get:
`4000cancel(pi)=4/3cancel(pi)r^3`
`r^3=3000`
`r=root3(3000)`

Surface of the sphere is:

`S=4pir^2`
We get:
`S=4piroot3(3000^2)=2613.9~~2614m^2`
