The volume of a cylinder with a radius r and a height h:

V_1=\pi r^2h

The volume of a cone with a radius r and a height h:

V_2=\dfrac{1}{3}\pi r^2h

Therefore

V_2=\dfrac{1}{3}V_1

We have V_1=32.25\ in^3

Substitute:

V_2=\dfrac{1}{3}\cdot32.25=10.75\ in^3

Answer: The volume of a cone is equal 10.75 in³

Which lines are parallel? Why?
Shtirlitz [24]

9514 1404 393

Answer:

  C) c || d by converse of corresponding angles

Step-by-step explanation:

Only corresponding angles where transversal b crosses lines c and d are shown. All answer choices involving a||b or interior angles can be eliminated from consideration.

The "corresponding angle" theorem tells you corresponding angles are congruent if the lines are parallel.

The converse of that theorem tells you the lines are parallel if the corresponding angles are congruent. Here, the angles are shown congruent, so the "converse" theorem applies.

13.50 for food
2.40 for drink

Since there is a voucher for 1/3 of food,

13.50 multiplied by 1/3 is 4.5 which is the discount

13.50-4.5=9

9 is the final cost for the food.

Add 9 to 2.40 for the drink which results in a total of 11.40

To find the amount charged for service you multiply 11.40 by .15

11.40 × .15 = 1.71

You add 1.71 to 11.40

The total is 13.11
