Question

perimeter of a semi circular field is 180m . calculate the diameter of a field​

Answer 1

Given that:

perimeter of a semi circular field is 180m

To Find:

diameter of a field

Solution;

perimeter of a semicircle = π r + d

So According to the question,

perimeter of a semi circular field is 180m

:. π r = 180

=> π r =180

=> r(22/7) =180

=> r= 180×7/22

=> r=1260/22

Now we have to Find the diameter of the field

diameter of the field = 2r

2r=d

2×1260/22=d

diameter of the field = 114.54
