The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
Answer:
European can holds more, Volume is approx 159π
American can, Volume is approx 149π
Step-by-step explanation:
V(cyl) = π · r² · h
25 a month x 12 months= 300
300+50= 350
56 weeks x 3 times a week= 168
350/168= 2.08 each visit
