Answer:

The surface area of the cylinder with a radius of 7 and height of 20 would be 1186.92.

Step-by-step explanation:

The formula as given by the image is

h=20, r=7.

Substitute your radius and height as follows:

SA= $SA=2*pi*r^2+2pi*r*h\\(2*3.14*7^2)+(2*3.14*7*20)$

And now solve!

307.72+879.2=1186.92

The answer would be 1186.92

Answer:

y = 4x + 9

week 21

Step-by-step explanation:

first I did 37-9 and got 28 I divide that by 7 ( seven weeks) and got 4 so I know the slope is 4.

so to find how many weeks till 93 I did; 93 = 4x + 9. We have to get x by its self so I minus 9 by both sides and got 84 = 4x. So now we divid both sides by 4 to get x by its self and we end up with 21 = x
