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 3 inches and below r equal to 3 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?
24%
36%
50%
64%

Best ResponseYou've already chosen the best response.1but you could solve for area. and then make those ratios

Best ResponseYou've already chosen the best response.1so yeah. find area. the formula is \(\pi r^{2}\)

Best ResponseYou've already chosen the best response.1let's start with the smaller circle: \(A=\pi r^{2}\) A=\(\pi 3^{2}\)

Best ResponseYou've already chosen the best response.1so multiply pi by 2.... what do you get? @Marc1313

Best ResponseYou've already chosen the best response.1i meant by 9..lol sorry xD since \(3^[2]\) is 9

Best ResponseYou've already chosen the best response.1yep. so that's the area of the smaller circle

Best ResponseYou've already chosen the best response.1can you find me the area of the larger circle?

Best ResponseYou've already chosen the best response.1just do it with this formula i used earlier \(A=\pi r^{2}\) \(A=pi 5^{2}\) which becomes \(A=\pi 25\)

Best ResponseYou've already chosen the best response.1multiply pi by 25 to find the area of the larger circle

Best ResponseYou've already chosen the best response.1@Marc1313 can you multiply pi by 25 to find the area of the larger circle?

Best ResponseYou've already chosen the best response.1there's one final step to find the answer...set the areas as a ratio, like so: \(\Large\frac{28.27}{78.54}\) ^^ then simplify it :)

Best ResponseYou've already chosen the best response.1cool. basically, find the areas, and then make a ratio (fancy way of saying division) :)

Best ResponseYou've already chosen the best response.1positive. I remember this unit now, lol i realized that it wasn't probability, it was just ratios :P
