Answer:

Step-by-step explanation:


Given:
Volume of the cone = π r² h/3
radius of the cone is half the radius of the cylinder ⇒ r/2
height of the cone is equal to the radius of the cylinder. ⇒ r
V = 3.14 * (r/2)² * r/3
V = 3.14 * r²/4 * r/3
V = 3.14r³ / 12
Answer: 2 cans.
Step-by-step explanation:
Calculate the volume of the go cart tank, which has the form of a rectangular prism. You can use the following formula:

Where:
l: is the lenght.
w: is the width.
h: is the height.
In this case:

Substitute values into the formula. Then:

If a gas can holds 1 gallon of gas and
, then the number of full gas cans that will take to fill the go cart's tank (whose volume is 462 in³) is:

I think you use
xamount(1-.8)
.8 being 80% as a decimal.
1 being 100%
so .2 or 20% remaining multiplied by whatever amount.
