Find the volume of a pyramid with a square base, where the side length of the base is 17 in and the height of the pyramid is 9 in. Round your answer to the nearest tenth of a cubic inch.

Answer 1

To find the volume of a pyramid, you can use the formula V = (1/3) * B * h, where B is the area of the base and h is the height of the pyramid.

First, find the area of the base:
Area of a square = side length * side length
Area of the base = 17 in * 17 in
Area of the base = 289 in²

Now, plug in the values into the formula:
V = (1/3) * 289 in² * 9 in
V = (1/3) * 2601 in³
V = 867 in³

So, the volume of the pyramid is 867 cubic inches.

Answer 2

Find the volume of the right cone. Found your answer if necessary

Height 17, across the circle 12

Answer 3

To find the volume of a cone, you can use the formula V = (1/3) * π * r^2 * h, where r is the radius of the circular base and h is the height of the cone.

Given:
Height (h) = 17
Radius (r) = 12/2 = 6

Now, plug in the values into the formula:
V = (1/3) * π * 6^2 * 17
V = (1/3) * π * 36 * 17
V = (1/3) * π * 612
V = 204π ≈ 640.4

So, the volume of the cone is 640.4 cubic units.

Answer 4

Wrong

Answer 5

I apologize for the error. Let's calculate it again:

Given:
Height (h) = 17
Radius (r) = 12/2 = 6

Now, plug in the values into the formula:
V = (1/3) * π * 6^2 * 17
V = (1/3) * π * 36 * 17
V = (1/3) * π * 612
V ≈ 646.2 cubic units

So, the correct volume of the cone is approximately 646.2 cubic units.

Answer 6

Vhat is the volume of a sphere with a radius of 31.6 cm, rounded to the nearest tenth of a cubic centimeter?

Answer 7

To find the volume of a sphere, you can use the formula V = (4/3) * π * r^3, where r is the radius of the sphere.

Given:
Radius (r) = 31.6 cm

Now, plug in the value into the formula:
V = (4/3) * π * (31.6)^3
V ≈ 106493.27 cubic centimeters

Rounded to the nearest tenth, the volume of the sphere is approximately 106493.3 cubic centimeters.
