If the radius of a circle proportional to the circumference of the circle. justify your answer. if the radius of a circle is 18 miles 1. what is the measure of the diameter. 2. what is the measure of the circumference, exactly in terms of pi. 3. what is approximate measure of the circumference, to the nearest tenth of a mile.

circumference of a circle (C)

C = πd or 2πr ( because d 2 x r)

r= 18 miles given

d= diameter

r= radius

d = 2 x r

d = 2 x 18 = 36 miles

2) C = πd

C = 3.14 x 36 = 113.04 miles

3) approximate measure of C = 22/7 x 36= 113.14 miles

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.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
