Question

The circular pond is surrounded by a 2m wide circular path

Answer 1

Answer:

here is your solution ☺☺☺

☺☺☺☺Suppose R be the outer circumference of circular path.

Outer circumference of circular path = 2πR = 44 m

⇒2×227×R = 44⇒R = 44×72×22 = 7

So, radius of inner circular path = radius of outer circular path - width of the path = 7 - 2 = 5 m

So, inner circumference of circular path = 2πR = 2×227×5 = 31.42 m

Area of the path = area of the outer circular path - area of inner circular path

= π72-π52= 227×49-227×25= 154-78.57= 75.43 m2
