Detailed Solution

We need to find the value of

π

in reference to a circle.
We know that the circumference of a circle is the total length of its boundary.
For a circle of radius ‘r’, the circumference is given as follows,
Circumference =

2 π r

Now, as the diameter of a circle say ‘d’ is twice its radius, so we can rewrite the above formula in terms of its radius as follows,
Circumference =

π (2 r) = π d

So, we get the value of

π

from the above formula as follows,

π = Circumference d

Hence, the correct option is (3).
