Answer:

Step-by-step explanation:
Circumference is the perimeter of a circle. It can be found using the formula:

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:

We know the circumference is 25.12 inches.

Let's round pi to 3.14

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.


Divide both sides by 2.


The radius of the disc is <u>4 inches.</u>
It is the graph where the two lines intersect, when they intersect there is a point where they connect, and that is your answer
Answer:
these are the step to follow so A=bh
Step-by-step explanation: A=1/2bh A=bh A=1/2 (b=b)h this is an example so you can follow how i did this
Y=mx+b is the slope intercept form where m=slope and b=y intercept
so
2y=x-4
divide both sides by 2
y=1/2x-2
slope is 1/2
