Answer:
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

Answer:
135
Step-by-step explanation:
:)
16 to 18 simplifies down to 8 to 9 because you divide 2 to both terms
24 to 27 simplifies down to 8 to 9 because you divide 3 to both terms
So yes
A
I’m not sure what that is
