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 \(=\) \(m^2\)
