Given:
A circle of radius r inscribed in a square.
To find:
The expression for the area of the shaded region.
Solution:
Area of a circle is:

Where, r is the radius of the circle.
Area of a square is:

Where, a is the side of the square.
A circle of radius r inscribed in a square. So, diameter of the circle is equal to the side of the square.

So, the area of the square is:


Now, the area of the shaded region is the difference between the area of the square and the area of the circle.




Therefore, the correct option is (a).
Answer:
Statistics can help solving data quantitative analysis data.
Step-by-step explanation:
Statistics can help solving data quantitative analysis data.
Examples of questions, that statistics can help provide answers to
- What is the measure of central tendency, that is representative of entire statistical data.
Ans : It can be found out by calculating mean , median , mode
- How widely dispersed or spread off is the data
Ans : It can be found out by calculating standard deviation, variance
Answer:
P = 24
Step-by-step explanation:
Since all the sides are the same length, the shape is a square.
Multiply all sides by 6.
6 cm x 4 sides = 24
150 114 84 60 42 30 24
from right to left the difference between numbers is increasing by an extra 6 each time
24 +6 =30 + 12 =42 +18 = 60 etc
It is true that the graph represents a function
<h3>How to determine if the graph represent a function?</h3>
For a graph to represent a function, the following must be true
Each x value on the graph must point to exactly one
The above means that the function must pass the vertical line test
The given graph would pass the vertical line test
This is so because:
Each x value on the graph points to exactly one
Hence, the graph represents a function
