As you can see, every time x increases by 2, y decreases by 5.
So, we have

Answer:

Step-by-step explanation:
Given

Required
The area of the semicircle
First, we calculate the hypotenuse (h) of the triangle
Considering only the triangle, we have:
--- cosine formula
Make h the subject



The area of the semicircle is then calculated as:

This gives:



d =√((x_2-x_1)²+(y_2-y_1)²)
This is the formula of distance between
So, I hope u will get all answer of the questions by using this formula...
Thanks...
