Question
Find the area of a circle whose radius is: $3.5\ m.$
✓
Answer
Radius of the circle $(r) =3.5\text{m}$
$\therefore\text{Area}=\pi\text{r}^2=\frac{22}{7}\times3.5\times3.5\text{m}^2$
$=38.5\text{m}^2$
$\therefore\text{Area}=\pi\text{r}^2=\frac{22}{7}\times3.5\times3.5\text{m}^2$
$=38.5\text{m}^2$
