Answer:
1 and 9/28
Step-by-step explanation:
you need to put everything over the same denominator
21/28+16/28=37/28
this can be written as 1 9/28
Assume that the radius of the circle is 1.
The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).
Finally, the ratio of the square to the circle, in area, will be
(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi
We can conclude that the white area is about 35%.
