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.

Answer:
3,6
Step-by-step explanation:
On simplifying the expression 13.8+ (-11.5) , we get 2.3 . And additions
13.8 + (-11.5) and (-13.8) + 11.5 are numbers will same value and opposite sign.
<h3>What are rules for adding a positive and a negative number?</h3>
For adding a negative and a positive number, use the sign of the larger number and subtract.
For example: (–8) + 2 = -6
Given that we have to solve 13.8 + (-11.5) = 13.8-11.5 (we subtract smaller no from larger and will use the sign of lager number that is + here)
13.8+(-11.5) = 13.8-11.5 =2.3
13.8+(-11.5) simply means that 13.8 -11.5 which is subtraction of 11.5 from 13.8
but (-13.8) + 11.5 = -13.8 +11.5 = -( 13.8 -11.5) [taking -1 common from the expression]
Therefore , -13.8 + 11.5 has same value as 13.8- 11.5 but opposite in sign.
