Question

2. In a building there are 24 cylindrical pillars with each having a radius 28 cm and height 4 m. Find the cost of painting the curved surface area of all pillars at the rate of Rs. 8 per meter square.

Answer 1

Radius=24cm=24/100m

Height=4m

After conversion of radius into meter, use the values in finding cylinders area

Now, after getting area multiply it by 24 for getting area of 24 pillars

Rate=8rs/m^2

Now, for getting cost multiply 8 with area of 24 pillars

The answer you get after above calculation will be your cost of painting.
