Question

If the radius of a circle is 35 m, then the circumference of a circle is:

• A. $110m$
• B. $220m$
• C. $70m$
• D. None of these

Answer 1

Answer: (B)

$220m$

Given that, the radius of a circle is, $r=35m$

To find out: The circumference of the circle.

We know that, the circumference of a circle is $2\pi r$

$\therefore$ Circumference of the given circle $=2\times \frac{22}{7}\times 35[\because \pi =\frac{22}{7}]$
$\therefore$ Circumference $=220m$

Hence, if the radius of a circle is $35m$, the circumference of the circle is $220m$.
