Question

if the circumference of a semi circle is 216 mts then is radius is

Answer 1

68.72 m

Step-by-step explanation:

Circumference of Semicircle of circle = $\frac{2 \pi r }{2}$

Where r is the radius

We are given that the circumference of a semi circle is 216 mts

So,  $\frac{2 \pi r }{2}=216$

$\pi r=216$

$\frac{22}{7}r=216$

$r=\frac{216}{\frac{22}{7}}$

$r=68.72$

Hence the radius is 68.72 m
