Question

If the area of a circular court is 616m square find the length of the wire required to fence it 3times.

Answer 1

hi there!!!

Solution:

here,

Area of school circular court= 616 m^2.

we know,

area of a circle=πr^2

hence,

616= πr^2

616=22 × r^2

7

616×7= r^2

22

28×7= r^2

196=r^2

√196= r

14= r

hence,

radius= 14 m

now,

circumference= 2×π×r

= 2×22× 14

7

= 2×22×2= 88

hence, circumference = 88m

Therefore,

length of wire for fencing three times = 3× 88= 264 m

hope this helps! ✌☺❤
