Recall, the volume of a cone is 1/3pi times radius of base times height.
Volume of a cylinder is the same but without the 1/3
It gives you the cone volume 20pi and that the radius and height of both of them are the same values.
since it says the radius and height are the same for both , you can equate the two, you can solve both equations for r^2*h and then equate what is on the other side.
so
