Given- diameter -1m- radius - diameter2-12height of cylinder -4-2 m

A building has $8$ right cylindrical pillars whose cross sectional diameter is $1$ m and whose height is $4.2$ m. Find the expenditure to paint these pillars at the rate of Rs. $24$ per $m^{2}$
Rs. $2534.40$
Rs. $2506.13$
Rs. $2610.9$
Rs. $2514.5$

Given, diameter $= 1$ m, radius $=$ $\frac{d i a m e t e r}{2} = \frac{1}{2}$
height of cylinder $= 4.2$ m
