Given
and
Expand:
Since the denominators are the same, they will cancel out,
There is no following, however
Motion, best describes the movement of an object.
Hope this helps!
That is called an equation
They give the formula as:
Surface Area =<span> (2 • <span>π <span>• r²) + (2 • <span>π • r • height)</span></span></span></span>
However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder. Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the <span>(2 • <span>π • r • height) part of the formula.
So, r = 3 inches and height = 8 * 3 inches, the side area equals
2 * PI * r * height
2 * 3.14159 * 3 * 24 =

452.39 cubic inches which is the lateral area.</span></span></span>
Cost/gallon
67.50/23 = x/1
23x = 67.50
23x/23 = 67.50/23
x = 2.93
they spent approximately $2.93 per gallon on gas
