Question

A vegetable Garden which is circular in shape. He wants to fence the garden at the rate of 15 ruppes per meter. find the cost of fence the garden if the radius of the garden is 21 metre? ​

Answer 1

answer-

radius = 21 meter

so the circumference = 2Лr

circumference = 2 * [22*7] * 21

we will cancel 21 with 7 and get 3

circumference = 2 * 22 * 3

circumference = 132 m

now cost of fencing per meter = 15

so, cost of total fencing of 132 meters = 132*15

= 1980

so, total cost of fencing = 1980 rupees

hope it helps

have a nice day
