Question

A right circular cone has a diameter of 10 radical 2 and a height of 12. What is the volume of the cone in terms of pi?

Answer 1

That volume would be:

V = (1/3)(base)(height) = (1/3) * (pi) *( 5sqrt(2) )^2 * 12
 
      25(2)*12*pi       600 pi
   = ---------------- = ------------ = 200pi (answer)
