Question

solid is in the form of a cone mounted on himispher in such away that the Venter of the base of the cone fast coincide with the center of the base of the hemisphere.the radius of hemisphere and height of cone are r each ,radius of base of cone is 1/2r and slant height of cone is l.find surface area and volume of the solid.
.
hemisphere: a = 2πr^2, v = 2/3 πr^3
cone: a = 2πrl, v = 1/3 πr^2h

Now plug in your values as needed. What do you get?
