Question

If the perimeter of a semi-circular park is 72m, find it's area and perimeter. solve it.

Answer 1

Perimeter of semi circle = 72 m

=> pi *r + 2r = 72

=> 22r/7 + 2r = 72

=> 36r/ 7 = 72

=> r = 72 * 7 / 36

=> r = 2* 7

=> r = 14 m

Area = pi *r^2 /2

= 22 * 14 * 14 / 2 * 7

= 22 * 14

= 308 m^2

Answer 2

Perimeter of semi circle = 72 m

=> pi *r + 2r = 72

=> 22r/7 + 2r = 72

=> 36r/ 7 = 72

=> r = 72 * 7 / 36

=> r = 2* 7

=> r = 14 m

Area = pi *r^2 /2

= 22 * 14 * 14 / 2 * 7

= 22 * 14

= 308 m^2
