Question

Find the cost of fencing a circular garden of radious 25 meters at the rate of 3 per meter take π=3.14

Answer 1

Since it's fenced, circumference is required to find it first.

Circumference = 2πr

= 2 × 3.14 × 25

= 157 m

Rate of fencing = ₹3 per metre

So total cost of painting = 157 × 3

= ₹471

Answer :- ₹471

Answer 2

Answer:

Step-by-step explanation:

Step 1 : The perimeter of a circle is given by 2πr where r is the radius

Step 2: Substituting the values in the formula we get

           2*3.14*25(radius)=157 meter sq.

Step 3: The cost of the fencing would be

            157*3=₹471

Final answer ₹471
