Question

Find the diameter of a circle whose circumference is: $88\ m.$

✓

Answer

Let the radius of the circle be $r\ m.$
Circumference of the circle $ (C) =88\text{m}$
$\Rightarrow2\times\frac{22}{7}\times\text{r}=88$
$\Rightarrow\text{r}=\frac{88\times7}{2\times22}=14\text{m}$
Now, diameter $=2\times\text{r}=2\times14=28\text{m}$
