Question

In a mosque there are 24 cylinder Pillars. The radius of each pillars is 28 cm and height is 4 m. Find the total cost of painting the curved surface area of all pillars at the rate of AED 8 per m2

Answer 1

Radius of cylinderical pillars
= r = 28cm =0.28m
height ,h=4m
curved surface area of a cylinder =2πrh
curved surface area of a pillar= 2×22\6×0.28×4=7.04metresq.
Curved surface area of 24 such pillars = 7.04×24=168.96metresq.
cost of cementing an area of 1metresq. =Rs8
so,cost of painting 1689.6metresq.=168.96×8=Rs1,351.68
