Answer:
what expression
Step-by-step explanation:
There are 3 types of cost for this problem: the cost for the area covered by the tiles, cost for hourly labor and the sales tax.
Cost of Area = (10.5 ft)(8 ft)($4.75) = $399
Cost of Hourly Labor = ($22/h)(7.5 h) = $165
Sum = $399 + $165 = $564
Cost of tax = $564(0.08) = $45.12
Total Cost = $564 + $45.12 = <em>$609.12</em>
So, the amount of the bill is incorrect.
1,691,040,000

Answer:
28π
Step-by-step explanation:
The formula for calculating surface area of cylinder is 2πrh+2πr^2 (r: radius, h : height)
Since the base for the given cylinder is 2 and height is 5 the surface area would be
2π×2×5 + 2π×2^2 = 28π
