Question

Find the surface area of a circular park having diameter 50m.

• A. 200$m^2$
• B. 1962.5$c{m}^2$
• C. 1962.5$m^2$
• D. 2000$c{m}^2$

Answer 1

The correct option is C

1962.5$m^2$

$Radius=\frac{1}{2}\times diameter=\frac{1}{2}\times 50=25m$
Surface area of circle =$\pi r^2$where $\pi =3.14$
$=3.14\times {25}^2=1962.5m^2$
