Volume of Spheres Flashcards

The volume of a sphere is calculated using the formula V = (4/3)πr³, where r is the radius.

'r' represents the radius of the sphere.

The volume of a sphere is measured in cubic units, such as cm³ or m³.

The radius is half the diameter. r = diameter ÷ 2.

If the radius is doubled, the volume increases by a factor of 2³ = 8.

The volume of a hemisphere is half the volume of a sphere: V = (2/3)πr³.

The constant π (pi) is approximately 3.14159, or 3.14 for estimation.

1. Find the radius. 2. Cube the radius (r³). 3. Multiply by π. 4. Multiply by 4/3.

The volume is V = (4/3)π(1³) = 4/3π cubic units.

The volume formula can be used to calculate the capacity of spherical objects, like a ball or a water droplet.
