Question

a man walks entirely around his semi -circular garden. what is the area of his garden, if he walks 324m?​

Answer 1

Answer:

area of his garden is 16690.70

Step-by-step explanation:

since the distance he walked around his semi-circular garden is 324m

that is even the perimeter of the semi-circle

perimeter of semicircle = 2πr/2 , which is πr.

value of 22/7

so, πr=324

r=324*7/22

r=162*7/11

r=1134/11

r=103.09m

now to find the area, area of semicircle=πr²/2

area= $} \frac{\frac{22}{7} *103.09^{2}}{2}$

area= (22*10621.36)/7*2

area= 233669.92/14

area= 16690.70 m²

maybe my answer is correct if it is helpful please mark me as brainliest.

thank you
