Answer:
≈ 2,826 cm^3
Step-by-step explanation:
V = πr^2h
V = 3.14 · 10^2 · 9
V = 3.14 · 100 · 9
V = 314 · 9
V = 2,826
Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
For the denominators (7, 13) the least common multiple (LCM<span>) is </span>91.
Therefore, the least common denominator (LCD<span>) is </span>91.
<span>Rewriting the original inputs as equivalent fractions with the </span>LCD:
<span>78/91, 49/91.</span>
