If the two solids have the same height and same cross-sectional area at every level, this means that the radius of the oblique cylinder is the same as the radius of the right cylinder.
Since the radius of the right cylinder is 16/2=8, this means that the radius of the oblique cylinder must also be 8.
Algebraically, the area of the cross-section is given by:
The bike will cost $481.50 because 10% off of 500 is 50 so 500 - 50 = 450 Now include the sales tax which is 450 * 0.07 = 31.5 Now add the two totals to get $481.50
