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
A.
2h
B.
2\(\pi\)h
C.
\(\pi\)h
D.
\(\frac{\pi h}{2}\)
Correct answer is A
\(\frac{x}{r}\) = \(\frac{x + h}{2r}\)
2 x r = r (x + h)
Total height of cone = x + h
but x = h
total height = 2h
