Answer 1

3/4

Explanation:

Let's say that r is the radius of the large circle or the diameter of the small circle.

Area of the big circle is
`\pi r^(2)` .

Area of the small circle is
`\pi (r)/(2) ^(2) = \pi (r^(2))/(4)`.

The ratio of these 2 circles is 1/4 (calculation in the comments).

So the shaded part represent 1 - 1/4 = 3/4.
