<u>Answer:</u>

<h3>
<u>Step-by-step explanation:</u></h3>
Given that the the diameter of a cylinder is 8 inches. the height is 12 inches. And we need to find its surface area .
Hence here ,
- Height = 12 inches
- Diameter of base = 8 inches
<u>Figure</u><u> </u><u>:</u><u>-</u>


<h3>
<u>★</u><u> </u><u>Hence</u><u> </u><u>the</u><u> </u><u>Surface</u><u> </u><u>area</u><u> </u><u>of </u><u>the </u><u>Cylinder</u><u> </u><u>is</u><u> </u><u>4</u><u>0</u><u>2</u><u>.</u><u>2</u><u>8</u><u> </u><u>in</u><u>.</u><u>³</u><u> </u><u>.</u></h3>
Answer:
3 seconds
Step-by-step explanation:
When the ball hits the ground, the height will be 0. Therefore, you can substitute 0 in for the value of f(t), hence the equation will be:
0 = -16t^2 + 32t + 48
You can then factor out -16:
0 = t^2 - 2t - 3
Factor:
0 = (t-3)(t+1)
t = 3, -1
However -1 is an extraneous solution because time cannot be negative. Therefore, the answer is 3 seconds.
-4x + 7 = 11
First, subtract 7 from both sides. / Your problem should look like:
Second, subtract 11 - 7. / Your problem should look like:
Third, divide both sides by -4. / Your problem should look like:
Fourth, change the fraction to a negative. / Your problem should look like:
Fifth, cancel 4 out. / Your problem should look like:

Answer:
x = -1
