Recall that the equation to solve for the volume of a cone is 1/3 * area of base * h
Since we have the radius and the height of the cone, we can put these into an equation:
1/3 * π(1.5)^2 * 4.5
(π(1.5)^2 is because we need to use the equation of the area of a circle in order to find the area of the base)
Square the 1.5:
1/3 * 2.25π * 4.5
The value of π is 3.14, so input that value:
1/3 * 2.25(3.14) * 4.5
Multiply 2.25 and 3.14:
1/3 * 7.065 * 4.5
Multiply all the values (You should use a calculator for this last part, since doing this by hand is a bit impractical):
1/3 * 7.065 * 4.5 = 10.5975
The sugar cone must be filled with 10.5975 cubic inches of ice cream.

Y=2.5r+50
Y is the total points
2.5 is the rate
r is the amount of questions he got right 50 is the score he already earned
D equals 4. Because 5D is like five times four.
A rational number is written in the form p/q, where p and q are not integers and q is not equal to 0.
An irrational number can be written in decimal form and possibly no end. In simple words, an irrational number cannot be expressed as a fraction.
