Question

The radius of a circular pool is 10.5m. Calculate the cost of flooring tiles used on the floor of the pool at the rate of Rs180/m square

Answer 1

11880 rupee is the answer

we have to find by formula 2πr where r is 10.5 and we get 66 and 180 rupee/m so multiply 66×180 and we get 11880

Answer 2

Answer:

r = 10.5m

area of circle = πr²

= 22/7×105/10×105/10

= 3465/10m²

cost = 180×3465/10

= ₹62370
