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,

answer:

1. 0.04

2. 0.15

step-by-step explanation:

i just finished that assignment for properties of probability distributions.

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
