Answer 1

Answer:

3/4

Step-by-step 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 $\pi \frac{r}{2} ^{2} = \pi \frac{r^{2}}{4}$.

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

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