At is the volume, in cubic meters, of a cylinder with a height of 4 meters and a base radius of 7 meters, to the nearest tenths place?

V = volume of cylinder, r = radius, h = height

In this case, r = 7 and h = 4.

V = pi*r^2*h

V = pi*7^2*4

V = pi*49*4

V = pi*196

V = 196pi  <<-- exact volume in terms of pi

V = 196*3.14159

V = 615.75 <<--- approximate volume

V = 615.8 <<--- rounding to 1 decimal place

i'm not sure i quite understand, could you provide more information?

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
