4. Example Problem IV

Mayank made a bird-bath for his garden in the shape of a cylinder with a hemispherical depression at one end (see Fig.). The height of the cylinder is $1.45 m$ and its radius is $30 cm$. Find the total surface area of the bird-bath. (take $\pi=\frac{22}{7}$

 

 

Total surface area of the bird-bath $=$ $m^2$
