A hemispherical bowl has a radius of $3.5 \mathrm{cm}$. What would be the volume of water it would contain?

A hemispherical and conical hole are scooped out of a solid wooden cylinder. Find the volume of the remaining solid where measurements are as follows:

The height of the cylinder is $7 \mathrm{cm}$, radius of each hemisphere, cone and cylinder is $3 \mathrm{cm}$. Height of cone is $3 \mathrm{cm}$. Give your answer correct to the nearest whole number. Take $\pi =\frac{22}{7}$.
