From the Wikipedia article about the radian: "The unit was formerly a SI supplementary unit, but this category was abolished in 1995 and the radian is now considered a SI derived unit." The radian can be derived as the ratio between two lengths. That makes it a dimensionless unit.
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Fundamental quantity
Volume is derived, from length.
Whether any quantity is a base quantity or a derived quantity depends on the definitions used in the system of measurements. In the SI, it is a derived quantity, defined as energy per unit charge. In units: joules/coulomb, where both joules and coulombs are also derived units.
A scalar quantity has an angle which is an even multiple of 90 degrees. A vector quantity has an angle which is an odd multiple of 90 degrees. A quaternion has any angle and includes the scalar and the vector; quaternion q = cos(angle) + unit-vector sin(angle)
Yes, area is a derived quantity.
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
the differentiate between fundamental quantity and derived quantity?

It is a derived quantity.
Current is a basic quantity, measured in amperes.
The derived quantity is a quantity which has been derived from 2 or more base quantities. Example: Velocity is the rate of change of distance and is written in terms of distance divided by time which are two base quantities.

yes it is,it is derived by cubing the fundamental unit of length
