Judy has a sugar cone and wants to know how many cubic inches of ice cream it will hold if it is filled completely to the top of
Romashka [77]
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.

Reptile [31]

Answer:

t = 26

Step-by-step explanation:

Step 1: Subtract 9 from both sides.

  • 9 + t - 9 = 35 - 9
  • t = 26

Step 2: Check if solution is correct.

  • 9 + 26 = 35
  • 35=35

Therefore, t = 26.
