Question

The figure below shows a shaded circular region inside a larger circle:

A shaded circle is shown inside another larger circle. The radius of the smaller circle is labeled as r and the radius of the larger circle is labeled as R. On the right side of the image is written r equal to 2 inches and below r equal to 2 inches is written R equal to 5 inches.

What is the probability that a point chosen inside the larger circle is not in the shaded region?

84%

50%

42%

Answer 11

x_x see im dead lol

Answer 12

Well really, I would assume 42%, because you need to calculate the AREA of the big and small circle and then as well subtract the area of the smaller circle to the area of the bigger circle.
The difference over the area of the bigger circle multiply by 100 will be the probability.
So yes 42%.
Nice job smartie (;
Hope this helps!
