Question

The dimensions of a cuboid are 44 cm, 21 cm, 12 cm. It is melted and a cone of height 24 cm is made. Find the radius of its base. ​

Answer 1

Answer:

Volume of cuboid=Volume of cone

$lbh = \frac{1}{3} \pi {r}^{2} h \\ 44 \times 21 \times 12 = \frac{1}{3} \times \frac{22}{7} \times {r}^{2} \times 24 \\ {r}^{2} = 21 \times 21 \\ r = 21cm$

Radius of base =21cm
