A tank of water has base a circle of radius 2 meters and vertical sides. If water leaves the tank at a rate of 5 liters per minute, how fast is the water level falling in centimeters per hour? (Remember that 1 liter is 1000 cubic centimeters.)

0.0398cm/min

Step-by-step explanation:

We are given that

Radius of base circle=r=2 m=

1 m=100 cm

1 L=1000 cubic cm

We know that

Volume of tank=

Differentiate w.r.t t

Substitute the values

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
