First you find the area of  both circles... The smaller one is Pi, and the other one is 1.75pi. Take 1.75pi and multiply it by 13, getting 22.75pi. Do the same for the other circle, getting 13pi. Now subtract the former number by the latter number, getting 9.75pi, and that is the volume.

A CD usually sells for $17.00. If the CD is 20% off, and sales tax is 5%, what is the total price of the CD, including tax?
Vedmedyk [2.9K]

Answer:

$14.28

Step-by-step explanation:

If the CD is $17 and is have a 20% off then you multiply .20 and 17 to get the amount that is off. Subtract that answer from 17 and you should get $13.60. That is the cost of the CD WITHOUT tax. To apply the tax, you multiply the cost and 0.05 (5%) to get 0.68. 0.68 is the tax cost. To get the entire cost of the CD, you add 0.68 (tax) and price (13.60) and get $14.28.
