A hemispherical depression is cut out from over a face of a cubical wooden block such that the diameter 'd' of the hemisphere is equal to the edge of the cube. Determine the surface area of the remaining solid.

Find the total surface area of a hemisphere of diameter $10 cm$.

The curved surface area of a hemisphere with radius $7 \mathrm{cm}$ is: 

(Take$\mathrm{\pi }=\frac{22}{7}$)

The surface area of a sphere of radius $7 cm$ is

(Take $\pi =\frac{22}{7}$)

The radius of a semi-sphere is $7$ cm, find the total surface area of it.

If the volume of a sphere is $4851 {\mathrm{cm}}^3$, then its surface area (in ${\mathrm{cm}}^2$) is: (Take $\mathrm{\pi }=\frac{22}{7}$)
