Question

a circular path of was circumference is 616 has the path inside the park was width is 14 m.All Around The Park find the area of Park excluding the path and also find the cost of grazing on it @ rupees 1.40 per metre square​

Answer 1

Answer:

a circular path of was circumference is 616 has the path inside the park was width is 14 m.All Around The Park. The area of Park excluding the path is 22176 m² and the cost of grazing on it @ rupees 1.40 per meter square​ is Rupees 31046.40

Step-by-step explanation:

From the given circumference we can get the radius of the path.

Circumference = πD

π = 22/7

616 = 22/7 × D

D = 616 × 7/22 = 196 m

D = 196 m

We can get the radius of the path.

Radius = 196/2 = 98 m

The radius of the park = 98 - 14 = 84 m

The area of the park is given by:

Area = πr²

Area = 22/7 × 84² = 22176 m²

rupees 1.40 per meter square

The cost of grazing = 22176 × 1.40 = Rupees 31046.40
