Based on the cylinder shown, which statement(s) are correct? A) If the volume is 577 cm^3, then the height of the cylinder is approximately 15 cm.
B) If the height is 10cm, then the volume of the cylinder is approximately 385 cm ^3.
C) If the height is 20 cm, then the volume of the cylinder is approximately 1070cm^3.
D)The equation V = π(3.5)^2h can be used to find the volume of the cylinder.
E) The equation h = V/π(7)^2 can be used to find the height of the cylinder.

answer: options?

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
