Question

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

Answer 1

Answer:

=52603.1 rs

Step-by-step explanation:

circumference of circular garden =2πr

=308m=2πr

=308/2=πr

=154=22/7×r

=154×7/22=r

=49m=r

area of circular garden=πr²

area of circular garden=22/7×49×49

=10846m²

cost of grazing=10846m²×4.85

=52603.1 rs

Answer 2

Answer:

7546m²

Step-by-step explanation:

Let the radius of the circle be r cm

Circumference of the circle=308

Therefore,

2πr=308

⇒r=

2×22

308×7

r=49m

Therefore,

Area of the circle=π×(49)
