Answer:
528in^3
Step-by-step explanation:
V=1/3πr^2h
V=1/3*22/7*6^2*14
V=1/3*22/7*36*14
V=1/3*22/7*504
V=528in^3
yes sure, i learned this before so
1. a. make a proportion here, of percentage. if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again, cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5

<u>Correct equation: A</u>
<u>16 − 4 x = 5</u>
