Question

If the perimeter of a semi circular park is 252 m, Find its Area​

Answer 1

Answer:

539 square meter

Step-by-step explanation:

Perimeter of a semi circular = πr +2r

πr+2r = 252

(22/7)*r + 2r = 252

22*r + 14r = 252 *7 ( multiplying both sides by 7)

36r = 252*7

r =252*7/36 = 7*7 = 343 m

Area of a semi circular park = 1/2 πr^ 2

= (1/2 )(22/7) * 343*

= 49 X 11

= 539 m^2

Ans = 539 square meter
