The height of water is increasing at the rate of 0.0194 meters per minute.
In mathematics, comparing two related quantities stated in different units is known as a rate.
If the denominator of the ratio is stated as a single unit of one of these variables and it is assumed that this quantity may be changed systematically, the numerator of the ratio is used to quantify the comparable rate of change in the other (depend) variable (i.e., is an independent variable).
Volume of the water filled in one minute = 3 cubic meters
radius is 7 m and height is h meters(say)
Hence volume = πr²h = 3
at r= 7,
π × 49 × h = 3
or, h = 3 / 49π
or, h = 0.0194 meters.
Hence the height of the water is rising at the rate of 0.0194 meters per minute.
