Practice objective / multiple choice question 36 from the 2021 Neco Model Questions Vol1 Mathematics examination.
A solid is formed by placing a right circular cone on top of a right circular cylinder. Both have the same base radius \(r\) cm and the cone's height is half the cylinder's height \(h\) cm. The total volume of the solid is \(432\pi\) cm\(^3\) and the total exterior surface area (the curved surface of the cylinder together with the curved surface of the cone, the base of the cylinder is not painted) is \(288\pi\) cm\(^2\). Find the ratio \(\dfrac{h}{r}\) correct to two decimal places.
