Question

A man walks entirely around his semi circular garden. what is the area of the garden if he walks 324 m​

Answer 1

Step-by-step explanation:

given half perimeter = 324 m

half perimeter of a circle is πr+2r = 324

=> r(π+2) = 324

=> r = 324 / (π+2)

=> r = 324 / (36/7)

=> r = (324*7)/36

=> r = 63 m

therefore are of tne garden = πr²/2

=> (22/7*63*63)/2

=> (22*63*63)/14 m²

=> 6237 m²
