PLS HELP! I NEED TO FIND THE SURFACE AREA OF THIS CYLINDER!
Contact [7]

Exact Surface Area = 378pi

Approximate Surface Area = 1186.92

The approximate surface area uses pi = 3.14

The units are cm^2 or "square cm".

=========================================================

Work Shown:

SA = surface area of cylinder

SA = 2*pi*r^2 + 2*pi*r*h

SA = 2*pi*7^2 + 2*pi*7*20

SA = 2*pi*49 + 2*pi*140

SA = 2*49*pi + 2*140*pi

SA = 98pi + 280pi

SA = 378pi ..... exact surface area

SA = 378*3.14

SA = 1186.92 ..... approximate surface area

----------

Side note: The diameter 14 cuts in half to get the radius r = 7

How do the constant of proportionality and slope relate to the unit rate
Pepsi [2]

Answer:

When a relationship is proportional, all y over x ratios simplify to the slope of the line which is the constant of proportionality or the unit rate, with one as a denominator. Example: Consider the equation y = 60x. The slope is 60. The rate of change is 60 units for every one unit.

M&lt;1=115<br> M&lt;2<br> Could y’all give answers for all though
Makovka662 [10]

Answer:

1) m<2 = 115°

2) m<5 = 83°

3) m<8 = 45°

4) m<4 = 137°

Step-by-step explanation:

When two lines cross over each other, creating four angles, the opposite angles are equal.

So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.

Similarly, in question two, <5 = <6 = 84°.

In question three, <8 = <9 = 45°.

and in question four, <3 = <4 =137°.
