The formula for SA of a cylinder is 2 pi r^2 + 2 pi r h
The 2 pi r^2 is for the circular top and bottom. In this case only the TOP is being painted so the 2 can be dropped.
SA = pi r^2 + 2 pi h
SA = pi 20^2 + 2 pi 20*60
SA = 400 pi + 2400 pi
SA = 2800pi ft^2
C

Answer:

The answer is 44.80 degrees

Step-by-step explanation:

First you want to find z

z = 180-(52+90)=38

and then try to determine which formula will try to give you x = Tan

Tan = Opposite/ Adjacent

Tan(38)=35/x

x=35/Tan(38)

x=44.80

The area of a parallelogram is modeled by the formula, A = lw. Solve the equation for w.
erastovalidia [21]
Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question today, and will teach you how to handle it on your own in the future.

First, let's look at our problem.
"A = L * W, solve for W."

This is basic algebra, but I will teach you how to tackle this problem, so you can do it on your own.

So, we have the following equation:
A = L * W
To solve for W, we need to get it alone on one side of the equation. Currently, it is not alone, but rather is being multiplied by L.
To isolate W, we need to perform the opposite order of operations on both sides of the equation.

A = L * W
Divide both sides by L to isolate and solve for W.

W = \frac{A}{L} is our solution.

The following equation matches the answer choice "C".

Your answer is "C."

I hope this helps!
