Question

Find the circumference of circle whose diameter is- $17.5cm$
Take $\pi =\frac{22}{7}$ in the above two questions.

• A. $55m$
• B. $25m$
• C. $59m$
• D. None of these

Answer 1

The correct option is A $55m$

Given: Diameter of circle $\left(d\right)=17.5m$

$\Rightarrow$ Radius of circle $\left(r\right)=\frac{17.5}{2}=8.75m$

Let $C$ be the circumference of circle,

$C=2\pi r=2\times \frac{22}{7}\times 8.75=55m$

So, $\text{A}$ is the correct option.
