Question

80 m diameter wale ek vrattakar park me andar maximum area ka ek vargakar play ground bna hai,what is the area of play ground?​

Answer 1

Given :-

• diameter of circle = 80m

To Find :-

• area of the play ground ?

Solution :-

Radius = diameter/2

• R = 80/2 = 40m

and we know that,

$\boxed{ \bold{area \: of \: circle = \pi {r}^{2} }}$

$\bold{: \implies \frac{22}{7} \times 40 \times 40 } \\ \\ \bold{: \implies \frac{35200}{7} } \: \: \: \: \: \: \: \: \: \: \: \: \:$

hence, area of play ground is 35200/7 m² or 5028.57.. m²
