Question

the circumference of the circular pond to be dug is 660m. Find the total cost for digging at the rate of Rs 660 per sq m.

Answer 1

Step-by-step explanation:

area of circular pond= 2πr×r

2×3.14×660×660

=2,962,080

cost=4488

Answer 2

Answer:

the circumference of a circle = 2πr = 660

then r = 660×7/2×22 = 210 m

then area of circle = πr^2 = 22/7 ×(210)^2 = 138600 m^2

then cost = 138600×660 = 91476000 rs
