Given a circle with a diameter of 4, which equation expresses π as the ratio of the circumference of a circle to its diameter?

Step-by-step explanation:

Circumference(C) of a circle is given by:

              ....[1]

where, r is the radius of the circle.

As per the statement:

Given a circle with a diameter of 4.

We know that:

Diameter(D) = 2r

⇒2r = 4

Substitute the value in [1] we have;

⇒

Divide both sides by 4 we have;

Therefore, the  the ratio of the circumference of a circle to its diameter is,

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
