Question
Find the area of the circle, given that: diameter: $= 49 m$
✓
Answer
$\text { Diameter }=49 \mathrm{~m}$
$\text { Radius }(r)=\frac{49}{2} \mathrm{~m}$
$\therefore \text { Area of the circle }=\pi \mathrm{r}^2$
$=\frac{22}{7}\left(\frac{49}{2}\right)^2 \mathrm{~m}^2$
$=\frac{22}{7} \times \frac{49}{2} \times \frac{49}{2} \mathrm{~m}^2$
$=\frac{3773}{2} \mathrm{~m}^2=1886.5 \mathrm{~m}^2$
$\text { Radius }(r)=\frac{49}{2} \mathrm{~m}$
$\therefore \text { Area of the circle }=\pi \mathrm{r}^2$
$=\frac{22}{7}\left(\frac{49}{2}\right)^2 \mathrm{~m}^2$
$=\frac{22}{7} \times \frac{49}{2} \times \frac{49}{2} \mathrm{~m}^2$
$=\frac{3773}{2} \mathrm{~m}^2=1886.5 \mathrm{~m}^2$
