Question

the perimeter of a semicircular garden is 180 metre. find the area of Garden ​

Answer 1

Step-by-step explanation:

PERIMETER = 180 M

πr = 180

22/7 × r = 180

r = 180×7/22

r=630/11 m

AREA = πr²

        = 22/7 × 630/11 × 630/11

       = 11340/11 m

Answer 2

perimeter of cemicircle= π r

180 = 22/7*r

r=57.27

area of semicircle =1/2π r square

=1/2 22/7 57.27*57.27

5154.05 m sq
