here,

diameter of cylinder = 50cm

so radius of cylinder = 25cm =

$\frac{25}{100} = 0.25m$

c.s.a. of cylinder =

$2\pi \: rh$

=

$2( \frac{22}{7} )(0.25)(3.5) \\ = \frac{385}{7} = 55 {m}^{2}$

so, curved surface area of cylinder is

$55 {m}^{2}$

total cost of white washing

= 55 × 1.25

= rs. 68.75
