Question

If the volume of a right circular cone of height 9 cm is 48 t cm", find the diameter of its
base.
kilolitre​

Answer 1

Answer:

$volume \: of \: cone \\ = \frac{\pi \times {r}^{2}h }{3} = 48 \\ r = \sqrt{ \frac{48 \times 3}{9\pi} } = 4 \sqrt{ \frac{1}{\pi} } \\ = 2.2567(approx) \\ diameter = 2r = 2 \times 2.2567 \\ = 4.5135 \: meter$
