Answer:
The right answer is A = 49.6 π ft^2
Step-by-step explanation:
<em><u>(Let pi = 3.1415926535898)</u></em>
<em>The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2</em>
<em>So if r = 4 ft</em>
<em>and h = 2.2 ft</em>
<em>A= 2π(4)(2.2)+2π(4)^2</em>
<em>Once we've plugged in our formulas our final surface area is A =</em><em> 49.6 π ft2</em>

Answer:

Step-by-step explanation:
There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is 
We have the function 
From this function, we can find that

We can plug in our know values into the formula to get

Then we can plug in our x-value to find the y-value of the vertex

This means that the vertex would be 
If you would like to know how many hours did Judd work outside, you can calculate this using the following steps:
40 hours
outside: 7/10 of the hours = 7/10 * 40 hours = 7/10 * 40 = 28 hours
Judd worked 28 hours outside.
Answer:
who
Step-by-step explanation:
-|20| + |5| = -15
Steps:
Apply absolute rule: |a| = a, a >/ 0
|20| = 20
= -20+5
Apply absolute rule: |a| = a, a >/ 0
|5| = 5
= -20+5
Refine
= -15
Hope this helps you! (:
