A cylinder with a radius of 5 stands upright in a closed cylinder box.If the volume of the cylinder is 100pi,what is the minimum value of the box?

Guys,I don't understand the concept.I got the height as 4 then reached a dead end.BTW,OA:D

The answer is 40/pi

First (pi)*5*5*h = 100pi, h = 4

so minimum vol. = diameter * diameter * height = 10*10*4 = 400

What is D?
