A circle is inscribed in a square. Write and simplify an expression for the ratio of the area of the square to the area of the c

STALIN [3.7K]

Best Answer:<span> </span><span>So first we need both areas, then we can relate them, and then divide the circle by the square:

A(circle) = πr^2
A(square) = L*W or (2r)*(2r) which is (2r)^2

For the square, we know this is true because because the radius is half the diameter, so if we multiply the radius by 2, we get the length of one side of the square. We also know that the lengths of both sides of the square are the same by definition of a square.

Ratio: (πr^2)/(4r^2) = π/4</span>

Please help me with a explanation

blagie [28]

Answer:

x = -3 or x = 3

Step-by-step explanation:

Subtract 9 from both sides.

x^2 - 9 = 0

Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.

(x + 3)(x - 3) = 0

Set each factor equal to zero.

x + 3 = 0 or x - 3 = 0

Solve each equation.

x = -3 or x = 3

part 3. Find the coordinates of the vertices of the triangle after a reflection across the y-axis and then across the line y= 2.

garik1379 [7]

Answer:

c. S'(3, 1), T'(1, -1), U'(0, 1)

Step-by-step explanation:

Reflection across the y-axis negates the x-coordinate, so is equivalent to the transformation ...

(x, y) ⇒ (-x, y)

Reflection across the horizontal line y=c is equivalent to the transformation ...

(x, y) ⇒ (x, 2c-y)

So, the combined reflections are equivalent to the transformation ...

(x, y) ⇒ (-x, 4 -y)

Then we have ...

S(-3, 3) ⇒ S'(-(-3), 4-3) = S'(3, 1)

T(-1, 5) ⇒ T'(-(-1), 4-5) = T'(1, -1)

U(0, 3) ⇒ U'(-(0), 4-3) = U'(0, 1) . . . . matches choice C
