<h3><u>Solution: </u></h3>

Radius of Cylindrical Pillar , r = 28 Cm = 0.28 m.

Height, h= 4 m.

Curved surface area of a Cylindrical = 2πrh.

Curved surface area of a pillar -

$= > \: 2 \times \frac{22}{7} \times 0.28 \times 4 = 7.04 {m}^{2}$

Curved surface area of 24 such Pillar :-

(7.04 x 24 = 168.96m²)..

Cost of painting an area of 1 m² = Rs8...

• Therefore , cost of painting 1689.6m² :-

( 168.96 x 8 = Rs 1351.68)...
