Answer:

\boxed {\boxed {\sf C. \ 4 \ inches}}

Step-by-step explanation:

Circumference is the perimeter of a circle. It can be found using the formula:

c= \pi d

However, we are given the radius.

  • The radius measures from the center to the edge of the circle.
  • The diameter measures from edge to edge through the center.
  • So, the diameter is twice the radius, or d=2r

The formula can be rewritten as:

c= \pi 2 r

We know the circumference is 25.12 inches.

25.12 \ in = \pi 2r

Let's round pi to 3.14

25.12 \ in = (3.14) 2r

We want to solve for the radius, so we must isolate it.

Divide both sides by 3.14 because the inverse of multiplication is division.

25.12 \ in / 3.14= (3.14 ) 2r  / 3.14

8 \ in = 2r

Divide both sides by 2.

8 \ in / 2 = 2r/2

4 \ in = r

The radius of the disc is <u>4 inches.</u>
