Answer:
13cm
Step-by-step explanation:
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.
-T.B.
WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
