Slant Height and Volume of a Right Circular Cone
Secondary 2
The diagram below shows a solid right circular cone with a curved surface area of \(144\pi \) cm\(^{2}\) and base radius \(9\) cm.
- Find the length of \(OP\).
- Find the volume of the solid cone, correct to \(1\) decimal place.
(Curved surface area of a cone\(=\pi rl\); Volume of a cone\(=\frac{1}{3}\pi {{r}^{2}}h\))
