For the question to have any meaning, the volume should be in cubic metres, not metres. The surface area of a sphere of radius r is 4*pi*r*r and its volume is 4/3*pi*r*r*r. Use the second equation to find the value of the radius, r and then use that value in the first equation to calculate the surface area.

a sphere
The surface area of a sphere is 4 pi R2A = 4 pi (5)2 = 100 pi = 314.16 square meters (rounded)
1) Calculate the area 2) Calculate the volume 3) Divide the area by the volume to get the ratio
