You can easily use online calculators for this.
Steps:
1) Find radius. 45 / 2 = 22.5
2) Substitute values (r) and (h) in the formula for surface area of a cylinder:
SA = 2πr² + 2πrh
3) Solve the formula.
You should end up with 9542.59 units². This answer is using π.
To get the answer with (3.14), do the steps above.
The domain is all the x values (range is y values). Remember to put the x values in numerical order.
So: Domain = {-5, -5, -2, 3}.
J.
x represents the minutes and y shows how many gallons over that time.
