Volume, Density, and Population Density

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

How do you calculate density?

Back

Density = mass/volume.

Front

What is the unit of density in the metric system?

Back

g/cm³ (grams per cubic centimeter).

Front

What is the relationship between mass, volume, and density?

Back

Mass is equal to density multiplied by volume (mass = density × volume).

Front

How do you convert cubic inches to gallons?

Back

1 gallon = 231 cubic inches.

Front

What is the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

If a cylinder has a diameter of 10 inches, what is the radius?

Back

Radius = diameter/2 = 5 inches.

Front

What is the volume of a cylinder with a radius of 3 inches and a height of 4 inches?

Back

Volume = π(3²)(4) ≈ 113.1 cubic inches.

Front

How do you find the surface area of a cylinder?

Back

Surface Area = 2πrh + 2πr², where r is the radius and h is the height.

Front

What is the density of an object that has a mass of 100g and occupies a volume of 50cm³?

Back

Density = 100g/50cm³ = 2g/cm³.
