The radius of a circle is 15. Using π, which equation expresses the ratio of the circumference to the diameter of a circle? Question 2 options: C30=π C=15πr C15=π C=r30π

The ratio of the circumference to the diameter of a circle is equal to

Step-by-step explanation:

we know that

The circumference of a circle is equal to

we have

----> the diameter is two times the radius

so

The ratio of the circumference to the diameter of a circle is equal to

simplify

Step-by-step explanation:

The circumference of the the circle with radius is  

,

and the diameter is 2 times the radius:  

.

Therefore, the ratio of the circumference to the diameter is

And since the diameter of our circle is

,

the ratio of the circumference to he diameter we get is

which can be rewritten as

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
