Example Question #1 :Know And Use The Formulas For The Volumes Of Cones, Cylinders, And Spheres: Ccss.Math.Content.8.G.C.9

Chestnut wood has a density of about. A right circular cone made out of chestnut wood has a height of three meters, and a base with a radius of two meters. What is its mass in kilograms (nearest whole kilogram)?

Possible Answers:

Correct answer:

Explanation:

First, convert the dimensions to cubic centimeters by multiplying by: the cone has height半径,它的基础.

Its volume is found by using the formula and the converted height and radius.

Now multiply this byto get the mass.

Finally, convert the answer to kilograms.

Example Question #2 :Know And Use The Formulas For The Volumes Of Cones, Cylinders, And Spheres: Ccss.Math.Content.8.G.C.9

A cone has the height of 4 meters and the circular base area of 4 square meters. If we want to fill out the cone with water (density =), what is the mass of required water (nearest whole kilogram)?

Possible Answers:

6333

Correct answer:

Explanation:

The volume of a cone is:

whereis the radius of the circular base, andis the height (the perpendicular distance from the base to the vertex).

As the circular base area is, so we can rewrite the volume formula as follows:

whereis the circular base area and known in this problem. So we can write:

We know that density is defined as mass per unit volume or:

Whereis the density;is the mass andis the volume. So we get:

Example Question #3 :Know And Use The Formulas For The Volumes Of Cones, Cylinders, And Spheres: Ccss.Math.Content.8.G.C.9

Possible Answers:

Correct answer:

Explanation:

The volume of a cone is:

whereis the radius of the circular base, andis the height (the perpendicular distance from the base to the vertex).

Example Question #4 :Know And Use The Formulas For The Volumes Of Cones, Cylinders, And Spheres: Ccss.Math.Content.8.G.C.9

A right cone has a volume of, a height ofand a radius of the circular base of. Find.

Possible Answers:

Correct answer:

Explanation:

The volume of a cone is given by:

whereis the radius of the circular base, andis the height; the perpendicular distance from the base to the vertex. Substitute the known values in the formula:

Example Question #5 :Know And Use The Formulas For The Volumes Of Cones, Cylinders, And Spheres: Ccss.Math.Content.8.G.C.9

A cone has a diameter ofand a height of. In cubic meters, what is the volume of this cone?

Possible Answers:

Correct answer:

Explanation:

First, divide the diameter in half to find the radius.

Now, use the formula to find the volume of the cone.

Example Question #1 :How To Find The Volume Of A Cone

A cone has a radius ofinches and a height ofinches. Find the volume of the cone.

Possible Answers:

Correct answer:

Explanation:

The volume of a cone is given by the formula:

Now, plug in the values of the radius and height to find the volume of the given cone.
