PLEASE HELP ASAP!!
Airida [17]

Answer:

C

Step-by-step explanation:

Hey There so the first step of this problem is to find the formula for circumference

C=2\pi r

given some of the values we can form an equation to solve for the radius (r)

31.4=3.14(2)r\\3.14(2)=6.28\\31.4=6.28r\\\frac{31.4}{6.28} =5

so we can conclude that the radius is equal to 5

What is the slope of a line that contains points (3, 10) and (3, -2)?
marishachu [46]

Slope is y2-y1/x2-x1

Let’s make the point (3,10) our x1 and y1 and let’s make (3,-2) our x2 and y2

-2-10/3-3

-12/0 = undefined

The slope is undefined. If it were to be 0/-12, the answer would be 0. If any number were to be divided by 0, it would be undefined.

Hope I helped!
