Help me solve it please

Step-by-step explanation:

(1) As definition, the area () of a circle is calculated by:

x with is radius of circle.

(2) The relation between radius () and diameter () of a circle is:

= 2 x

(3) Applying the Pythagorean theorem for a square with sides of length ,

the relation between side and diagonal is:

=> The diagonal () of that square is calculated by:

=

(4) The square fits exactly inside a circle, with each of its vertices being on the circumference of the circle.

Applying the theorem of inscribed angle in a circle, the measure of arc BD is twice as the measure of inscribed angle BAD.

In other words, the measure of arc AC = 2 x 90 = 180 deg, or half of circle.

It means that the diagonal BD is coincide with a diameter of circle.

=>

or x =

or =

Substitute back into original formula used for calculating the area of circle:

=> A = x = x

=> x

=> x = x = 5.97 cm

Hope this helps!

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
