Answer 2

Answer:

396 rupees

Step-by-step explanation:

diameter of cylindrical shape pillar is 48 cm then radius (r) = 48/2=24 cm

height (h)=7 meters = 700 cm

15 pillars surface area (a) = 15 ×2πrh

= 15 × 2×22/7×24×700

=158400 cm square

changing this into meters = 158.4 meter square

cost ofpainting for one meter square = 2.50 rupees

cost of painting for 158.4 meters square =158.4×2.50 = 396 rupees
