Question

Two identical cones share a circular base of radius 5 cm; each cone has vertical height 12 cm. Find the total volume, using $\pi=3.142$ where needed. Give decimal answers to 2 d.p. $h=12\text{ cm}$ $r=5\text{ cm}$ $12\text{ cm}$ Central section

Accepted Answer

Each cone has volume $\dfrac13\pi(5)^2(12)=100\pi\text{ cm}^3$. Total volume $=200\pi=628.40\text{ cm}^3$.
