Question

If the circumference of a circular garden is 308m,find its area . Also ,find the cost of grassing it at 4.85 per m2

Answer 1

Answer:

Circumference of the circular garden = 308m

Therefore 2πr = 308m

=> 2 × 22/7 × r = 308m

=> 44/7 × r = 308m

=> r = 308/1 × 7/44

=> r = 7 × 7

=> r = 49m

Area of the circular garden = πr²

= 22/7 × 49 × 49

= 22 × 7 × 49

= 7546m²

Total cost of grassing the land at the rate of ₹4.85 per m² = 7546 × 4.85

= ₹36598.1
