The volume of a cylinder is 32.25 cubic inches. If a cone has the same height and radius as the cylinder, what is its volume?
PtichkaEL [24]

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

Answer:

  1. 33.0 m
  2. 26.1 mi
  3. 28.0 mi
  4. 33.0 mi

Step-by-step explanation:

In each of these Law of Sines problems, you are given side a and angles B and C and asked for side c (problems 1, 3, 4) or side b (problem 2). The solution is basically the same for each:

Find the missing angle. Find the side from ...

  c = a·sin(C)/sin(A)

__

1. angle A = 180°-89°-58° = 33°

  c = (18 m)sin(89°)/sin(33°) ≈ 33.0 m

__

2. angle C = 180°-13°-17° = 150°

  b = (58 mi)sin(13°)/sin(150°) ≈ 26.1 mi

__

3. angle A = 180°-61°-89° = 30°

  c = (16 mi)sin(61°)/sin(30°) = 28.0 mi

__

4. angle A = 180°-39°-127° = 14°

  c = (10 mi)sin(127°)/sin(14°) ≈ 33.0 mi
