Question

A hemispherical bowl of internal radius $18cm$ contains an edible oil to be filled in cylindrical bottles of radius $3cm$ and height $9cm$. How many bottles are required to empty the bowl?

Answer 1

The radius of bowl $18cm$

The volume of bowl $2\pi r^{2}2\times \pi \times 18\times 18648\pi c{m}^2$

The volume of cylinder is $\pi r^{2}h9\left(9\right)\pi =81\pi c{m}^2$

No .of bottles is $\frac{648\pi }{81\pi }=8$
