The volume V of a right circular cylinder of radius r and height h is V=πr2h. (a) How is dVdt related to drdt if h is constant and r varies with time? (Enter drdt as dr/dt.)

Step-by-step explanation:

Given that the  volume V of a right circular cylinder of radius r and height h is

To find rate of change of V with respect to rate of change of radius

Here given that h is constant

So differentiation with respect to t gives

This would be dv/dt i.e. rate of change of volume with respect to time in terms of dr/dt

This varies whenever r varies

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
