To find the volume of a cylinder, you use this formula:
V =
![\pi](https://tex.z-dn.net/?f=%20%5Cpi%20)
![r^{2}](https://tex.z-dn.net/?f=%20r%5E%7B2%7D%20)
h
Plug in your numbers,
V = (3.14 *
![8^{2}](https://tex.z-dn.net/?f=%208%5E%7B2%7D%20)
) * 13
Exponents:
V = (3.14 * 64) * 13
Parentheses:
V = 200.96 * 13
Multiply:
V =
48 * .5 = 24
24 the amount of money discounted off the price
Therefore it would be 48 - 24 = 24, but then comes the sales tax.
Do 24 * .045 = 1.08
1.08 is the amount of tax owed on the game so you'd do
24 + 1.08 = 25.08
A) The total cost for the game is 25.08
B) Unfortunately he is short by 8 cents and won't be able to buy the video game he wants.

Step-by-step explanation:
The base is twice the height, or b = 2h. So, h = b/2. The area of a right triangle is (1/2)*b*h, and replacing h with b/2 you have (1/2)*b*(b/2), or (1/4)*b^2.So to write this it is<span> A(b) = (1/4)*b^2 for b >= 0</span>
