Answer:
24
Step-by-step explanation:
Use the triangle area formula: A=1/2 (base)(height)
Plug in what we know: 216=1/2(18)(h)
Solve for h: (1/2)(18)=9.
216/9=24.
So, h=24
To check, plug it into the formula: 1/2(18)(24)= 216
(1,1) —> (-4,-1)
(5,1)—> (-1,1)
(3,3)—> (-3,3)
C. 55 gallons because the formula for cylinder volume is V=pi•radius^2•height. So plug in the given values like in the pic below and then divide that by 231 to find the gallons
