Question

if the area of a semi circular park is 72 M . find its area and radius

Answer 1

Answer:

SEMICIRCLE ARES = 72 CM

==> 1/2×π×R² = 72

==> R² = 72×2×7/22

==> R² = 72×7/11

==> R² = 504/11

==> R = √504/11

AREA OF CIRCLE ==> πR²

AREA = 22/7×(√504/11)²

AREA = 22/7 × 504/11

AREA = 22×72 / 11

AREA = 2×72

AREA = 144
