Find the area of the shaded region. Leave your answer in terms of pi.

Step-by-step explanation:

First, find the area of the rectangle:

In order to find the area of the shaded region, we can subtract the areas of the two sectors from the total area of the rectangle.

Find the area of the sectors. We can use the sector formula:

The left sector has a radius of three units and an angle of 90°. Hence, its area is:

The right sector is identical to the left sector. So, the total area of the two sectors is:

Hence, the area of the shaded region is:

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.
