The radius of the larger circle is 10 cm. the radius of the smaller circle is 3 cm. what is the approximate area of the shaded region?

the large shaded circle containing a smaller white circle inside the larger circle.

question options:

70.7 square centimeters

86.5 square centimeters

102.4 square centimeters

285.74 square centimeters

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the larger circle minus the area of the smaller circle

so

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.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
