Question

2. What is the radius of a circle whose circumference is π?

Answer 1

Answer: 0.5 units.

Step-by-step explanation:

The circumference of a circle is given by :-

$C=2\pi r$, where r is radius.  (1)

Given : Circumference of circle :  $\C=pi$ (2)

From (1) and (2), we have

$2\pi r=\pi$

Cancel $\pi$ from both sides , we get

$2r=1\\\\ r=\dfrac{1}{2}=0.5$

Hence, the radius of circle = 0.5 units.
