the water in a fish tank is decreasing at a rate of 2 inches per hour

Rate of change is the derivative

Rate of change in height with respect to time  is 2 inches per hour

so

(a)

the unit of area is always units^2

so da/dt is the rate of change in area with respect to time

(b)

r is the radius

so dr/dt is the rate of change in radius with respect to time

Radius is decreasing at the rate of  40 cm per minute

(c)

v is the volume . the unit of volume is always cubic units
