Here's the solution ~
As we know, we can calculate the circumference of a circle in terms of its diameter as :
[tex]\qquad \sfΒ \dashrightarrow \:c = \pi d[/tex]
where, c = circumference and d = diameter
And also, circumference of circle is terms of radius (r) is :
[tex]\qquad \sfΒ \dashrightarrow \:c = 2\pi r[/tex]
Now, let's move on to questions ~
