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%
16%

Answer 1

this one remember @jackmullen55

Answer 3

So the area of the big circle is 78.54 and the area of the little circle is 12.57.

Answer 4

0.0 how?

Answer 5

It just is r^2•pi

Answer 6

So 12.57 is 16% of 78.54 so the probability that a point chosen is not in the shaded are is 84%
100 - 16 = 84

Answer 7

0.0

Answer 8

woah
