6. a square is inscribed in a circle. the sic
length of the square is 4 centimeters,
calculate the area of the shaded region.

9.13 cm^2.

Step-by-step explanation:

The diagonal of the square = the diameter of the circle.

The length of the diagonal = 4√2 cm (because we have a 45-45-90 triangle), so the radius of the circle is half of this = 2√2 cm.

The area of the shaded part = area of the circle - area of the square

= π (2√2)^2 - 4^2

=  25.13 - 16

= 9.13 cm^2.

what grade level is this? need to know so i can look in my old textbooks!

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
