Question

If the perimeter of a semi -circular park is 72m ,find its area and radius.​

Answer 1

Answer:

Area = 824.728 m ^ 2

R = 22.91 m

Step-by-step explanation:

Perimeter ( p ) = 72 m

Area ( A ) = ?

Radius ( R ) = ?

We know that ,

P = π r

72 = 22/7 × r

r = 22.91 m

A = π r ^ 2 / 2

$\frac{ \frac{22}{7} \times {22.91}^{2} }{2}$

824.728 m ^ 2
