The diagram above shows a cone with the dimensions of its frustrum indicated. Calculate the height of the cone.
12cm
15cm
18cm
24cm
30cm
Correct answer is D
Considering the smaller and larger triangle, these two are similar triangles. Hence,
If the height of the smaller triangle = h,
∴
12h = 6h + 72 \implies 6h = 72
h = 12 cm
\therefore The height of the cone = 12 + 12 = 24 cm
