Question

The diagram shows a sand pit in a child's play are. The shape of the sand pit is a sector of a circle of radius 2.25m and sector angle ${56}^0.$ Calculate the area of the a sand pit.

Answer 1

Area of sector $=\frac{\theta }{360}\times \pi r^2$

$=\frac{56}{360}\times 3.14\times (2.25{)}^2$ ...{As our $\theta ={56}^o$}

$=\frac{56}{360}\times 15.89625$

$=2.474m^2$.
