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

B. π = 8C/5

Step-by-step explanation:

Given the following data;

Diameter = ⅝

To find the ratio;

Mathematically, the circumference of a circle is given by the formula;

C = πD

Where;

C is the circumference of a circle.

D is the diameter of a circle.

Substituting the value of D, we have;

C = π * ⅝

Cross-multiplying, we have;

8C = 5π

π = 8C/5

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
