A toy is made from a cylinder with two identical hemispheres attached to the sides. The cylinder has radius r cm and height 36r cm. Below is the cross sectional view of the toy: r cm 36r cm The sum of volumes of the two hemispheres is equal to the volume of the cylinder. Show that the radius of the hemisphere is 3 times the radius of the cylinder. Hence, in terms of r and t, find the total surface area of the toy.
