Answer:
<em>y = - </em>
<em> x + </em>
<em> </em>
Step-by-step explanation:
y = 12x - 9
Slope of line perpendicular to given is m = -
P(7, 10)
y - 10 = -
(x - 7)
<em>y = - </em>
<em> x + </em>

To solve the area of a cylinder, you need to do steps.
Calculate volume of a cylinder: V = πr2h.
...
Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh.
...
Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr. ...
Total surface area of a closed cylinder is:
439.82 square inches
