Question

A cylinder shaped water tank has a diameter of 8 m and a height of 20 m.

What volume of water does the tank contain when it is 60% full?

Use 3.14 to approximate pi.
Enter your answer as a decimal to the hundredths place in the box.

___ m3

Answer 1

Answer:

602.88 cu ft.

Step-by-step explanation:

V = Bh where B is the area of the base, which is a circle in your problem.

Since the diameter is 8, the radius is 4.

So, B = $\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24$

V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank

60% of that volume is .60(1004.8) = 602.88 cu ft.
