Question

The diameter of a circle is 8mm. What is the circumference of the circle?

Answer 1

Answer:

12.56 $mm^{2}$

Step-by-step explanation:

c = 2$\pi$r

or c =$\pi$D

The diameter is the measure of a line segment going from one side the circle to the other and going through the middle of the circle.  A radius is a line 1/2 a diameter.  It is a line segment that goes from the center of a circle to a point on the edge of the circle.

C = (3.14)(4)

C = 12.56

Answer 2

Answer: 8π mm (in terms of π)

Step-by-step explanation:

1) The formulas for solving the circumference of a circle is πd (π times diameter).

2) 8 times π equals 8π mm.
