Answer:

Step-by-step explanation:
GIVEN: A square with base
, a circle that perfectly fits inside square.
TO FIND: Approximate area of circle.
SOLUTION:
Consider the figure attached.
let the radius of circle be 
radius of circle 


Area of circle 


Hence the area of circle that perfectly fits inside the square is 
The answer for the first blank is 36 and the answer for the second blank is 97.
To complete the square, we first take half of the value of b. The value of b in this equation is -12; -12/2 = -6.
Next we square the value we just got: (-6)² = 36.
This is what we add to both sides of the equation, giving us:
x²-12x+36=61+36
Combining like terms on the right, we have
x²-12x+36=97
You need to add up all the sides to find the perimeter.
Y = -2x - 4
x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5
y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6
Solution set {-5, 6} (C)
The answer is x equals -3
