To solve the problem, get first the area of the circle and the square -
Circle -> Area = pi * r^2; r= radius
= 3.14 * 1.5^2m^2 (radius is 1/2 of diameter)
= 3.14 * 2.25m^2
= 7.065m^2 or 7.07m^2 when rounded-off
Square -> Area = a^2; a = side
= 3^2m^2
= 9m^2
You can now perform the subtraction process -
9.00m^2 - 7.07m^2 = 1.93m^2
Therefore, 1.93m^2 is the difference between the area of circle and square
The percentage of the pages in the user manual that do not have diagrams is 0.8%.
<h3>What is the percentage?</h3>
Percentage is a measure of frequency that is is used to determine the fraction of an amount that is usually expressed as a number out of hundred.
Percentage without diagram = (4/500) x 100 = 0.8%

This is a true statement.
Consider two events A and B. We say they are complementary if P(A)+P(B) = 1
This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.
---------
Example:
A = the event it rains
B = the event it does not rain
P(A) = 0.30 = 30% chance of rain
P(B) = 0.70 = 70% chance it does not rain
P(A)+P(B) = 0.30+0.70 = 1
So this shows the two events are complementary.
