Question

the floor of the circular swimming pool whose radius is 7m has to be cemented at a rate of rs.18 per m². find the total cost of cementing the floor​

Answer 1

Answer:

Given,

Radius of swimming pool = 7m

We know that,

Area of the circle= 22/7 x r^2

So, 22/7 X 7 x 7

22 x 7

154 m^2

Given that,

Rate of cementing the floor for m^2= 18

Rate of cementing the floor for 154m^2 = 2772
