eviant:

A sphere has a surface area of 36π ft^2. Find the volume of the sphere.

eviant:

@dude @Narad

Narad:

The surface area of a sphere is \ The volume of a sphere is \[V=4/3*\pi*r^3\] whre r is the radius of the sphere You are give S=36pi Therefore, you can calculate the radius r Once you have the radius, you can calculate the volume

eviant:

@Narad would 36 be the radius, or 13?

Narad:

The surface area is \ r is the radius of the sphere \ Therefore, you can calculate the radius r

Narad:

The surface area is S= 4*pi*r^2

eviant:

@Narad is 36pi the correct answer?

eviant:

@Narad you there?

Narad:

S=36pi From this, you can calculate r
