The circumference of a circle is C centimeters. The diameter of the circle is 13 centimeters .

  OPTION C.

π =

Step-by-step explanation:

To find the expression that best represents the value of π if the  circumference of a circle is C centimeters and the diameter of the circle is 13 centimeters, we will follow the steps below;

Write the formula for finding the circumference of a circle

c = 2π r

where c is the circumference of the circle and r is the radius of the circle

from the question given,   diameter d is 13 cm

but d= 2r   which implies r=d/2

r = 13/2

c = 2πr

c=2×π×

At the right-hand side of the equation, 2 will cancel-out 2

c= 13π

divide both-side of the equation by 13

 =  π

π =
