Question
Find the circumference of a circle whose radius is: $28\ cm.$
✓
Answer
Radius of the circle $(r) = 28\ cm$
$\therefore\text{Circumference}=2\pi\text{r}$
$=2\times\frac{22}{7}\times28\text{cm}$
$=176\text{cm}$
$\therefore\text{Circumference}=2\pi\text{r}$
$=2\times\frac{22}{7}\times28\text{cm}$
$=176\text{cm}$
