Text Book Maths Problem - 2

Question

          
where V is the volume of a sphere
and S is its surface area.

 

Determine S, correct to 2 decimal places, if V = 780 x 10-3 m3

Answer 1

The Volume of a sphere = 4/3 pi r³

 

The Area of sphere = 4 pi r²

 

So, solve the first equation for r, and then use that value to find the surface area
