The volume of the perfume bottle can be calculated using the formula V = πr^2h.
Given:
Radius (r) = 6.2 cm
Height (h) = 12.4 cm
Now, substituting the given values into the formula:
V = 3.14 x (6.2)^2 x 12.4
V = 3.14 x 38.44 x 12.4
V ≈ 1507.808 cm³
Therefore, the volume of the perfume bottle is approximately 1507.808 cm³.

To find the best buy per cubic centimeter of perfume, we need to calculate the cost per cubic centimeter for each type of bottle.
For the cylindrical bottle:
Given:
Volume (V) = 1507.808 cm³
Price (P) = $54.00
Cost per cubic centimeter = Price / Volume
Cost per cubic centimeter = $54.00 / 1507.808 cm³
For the conical bottle:
Given:
Volume (V) = 1/3 * π * r^2 * h, where r is the radius and h is the height.
Radius (r) = 6.2 cm
Height (h) = 12.4 cm
Price (P) = $20.00
Now, substituting the given values into the volume formula:
V = 1/3 * 3.14 * (6.2)^2 * 12.4
V ≈ 3.14 * 38.44 * 12.4 / 3
Volume ≈ 2014.518 cm³
Cost per cubic centimeter = Price / Volume
Cost per cubic centimeter = $20.00 / 2014.518 cm³
For the spherical bottle:
Given:
Volume (V) = 4/3 * π * r^3, where r is the radius.
Radius (r) = 6.2 cm
Price (P) = $35.00
Now, substituting the given values into the volume formula:
V = 4/3 * 3.14 * (6.2)^3
V ≈ 4/3 * 3.14 * 238.328
Volume ≈ 1002.848 cm³
Cost per cubic centimeter = Price / Volume
Cost per cubic centimeter = $35.00 / 1002.848 cm³
Now, comparing the cost per cubic centimeter for each bottle:
Cylindrical bottle: $54.00 / 1507.808 cm³ ≈ $0.0358/cm³
Conical bottle: $20.00 / 2014.518 cm³ ≈ $0.0099/cm³
Spherical bottle: $35.00 / 1002.848 cm³ ≈ $0.0349/cm³
The conical bottle is the best buy per cubic centimeter of perfume because it has the lowest cost per cubic centimeter ($0.0099/cm³) among the three options.
For the cylindrical bottle:
