Answer:
0.2146
Step-by-step explanation:
From the picture:
The radius of the circle = r. This means that the area of the circle = πr²
Also For the square, the length of the square = 2r, Therefore the area of the square = Length × length = 2r × 2r = 4r²
The area inside the square but outside the circle = Area of square - Area of circle = 4r² - πr² = r²(4 - π) = 0.8584r²
The ratio of the area inside the square but outside the circle to the area of the square = r²(4 - π) / 4r² = (4 - π) / 4 = 1 - π/4 = 0.2146
Answer:
Step-by-step explanation:
We are given the following in the question:
Let P be the number of professor and S be the student in a college.
According to the question:
There are 19 times as many students as professors.
We have to write an equation to show the given relationship between professors and students.

The above situation is the situation that represents the given relationship.
Answer:
21x²
Step-by-step explanation:
hopefully A is a typo
Answer:
I'll edit the answer, but what are the equations?
Answer:
The slope is 2. (m=2).
Step-by-step explanation:
y+5=2x+2
y+5-5=2x+2-5
y=2x-3
Equation is y=2x-3.
y=y-intercept
x=slope
Hence, the slope is 2.
Hope this helps and stay safe!
