The height of a right cylinder is 3 times the radius of the base. the volume of the cylinder is 243 cubic units.
what is the height of the cylinder?
o2 units
4 units
o 6 units
8 units

Step-by-step explanation:

Height of a right cylinder = h

Radius of a right cylinder = r

according to the question,

3r = h or r = h/3

Volume,

πr²h = 243

or, π(h/3)²h=243

or, π×h²×h/9 = 243

or, h³=243×9/π

or, h=³√(243×9/π)

or, h = 8.86 (approximately)

This is what I'm getting

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer is : muchas/tipicas

have a nice day!
