Answer 2

Answer:

Given:-

The cost of fencing a circular garden at the rate of 25 per metre is 5500.

To Find:-

Find the radius of the garden.

Concept:-

Firstly let's understand the concept used here.It is Circumference of a circle.As we know,fencing is done throughout the round.So,we should find the perimeter.Substitute the values in the equation.Then,from it we can find the radius.

Solution:-

Let the circumference of the circle be Ym.

1m = Rs 25

So,

☞Ym = 25Y

According to the Question we have!!

25y = 5500

y = 5500/25

y = 220

y = 220m

☞Perimeter = 220m.

Circumference of circle = 2πr

= 2 × 22/7 × r = 220

= 44/7r = 220

= r = 220 × 7/44

= r = 35.

Therefore,

☞The radius of the circular garden is 35m.

Verification:-

Circumference = 2πr

r = 35

2 × 22/7 × 35 = 220

44/7 × 35 = 220

220 = 220

LHS = RHS

Hence,

☞It is verified.
