------------------------------
Given Area, find radius 
-------------------------------

Area = πr²

πr² = 452.16 mm²

r² = 452.16 ÷ π

r² = 143.93 mm

r = √143.93

r = 12mm

---------------------------------------
Radius Found, Find Diameter
---------------------------------------

D = r x 2 

D = 12 x 2 = 24 mm

Can someone help me find the slope?
kipiarov [429]

Answer:

Undefined

Step-by-step explanation:

First, take 2 points from the table given, then you use the equation y2-y1/x2-x1 to find your slope. So, if I take the coordinates (7,1) and (7,2) and plug them into my equation, I would get 2-1/7-7. If you solve this equation, you will end up wil 1/0. Now, if you have something like this as your answer, you can not find your slope. There can not be a slope because the zero is at the bottom, making this "Undefined".
