The sphere has radius 6 cm. The solid cylinder has a base radius of 3cm and a height of h cm. The total surface area of the cylinder is twice the total surface area of the sphere. Work out the ratio of the volume of the sphere to the volume of the cylinder. Give your answer in its simplest form. You must show all your working
Volume of a Sphere: 4/3πr^3 Area of a Sphere: 4πr^2 Area of a Circle: πr^2 Circumference of a Circle: 2πr Volume of a prism: BasexHeight
Volume of this sphere: 288π. Area of this sphere: 144π. Volume of this prism = 405π Ratio = 32:45
