In the frustum of the cone, the top diagram is twice the bottom diameter. If the height of the frustum is h centimeters, find he height of the cone
-
2h
- 2\(\pi\)h
- \(\pi\)h
- \(\frac{\pi h}{2}\)
The correct answer is: A
Explanation
2 x r = r (x + h)
Total height of cone = x + h
but x = h
total height = 2h
