A rectangular mat has a length of 12 in. and a width of 4 in. Drawn on the mat are three circles. Each circle has a radius of 2 in. Some friends play a game throwing darts onto the mat to see who can land a dart in one of the circles. Assuming that a dart always lands on the mat, what is the probability that a dart thrown at random will land inside one of the circles? Use 3.14 to estimate Pi. Enter your answer, as a decimal rounded to the nearest hundredth, in the box.

Answer:

0.79

Step-by-step explanation:

First you have to get the area of the whole figure/mat which you would get by multiplying 12 by 4, which gives you 48. Put that as a denominator and set it aside. For the numerator, get the circle's area (pi  x r^2). So 3.14 x 2^2= 12.56. Multiply that by 3 (because there are three circles in the mat) and you get 37.68 for your numerator. Divide 37.68(numerator) by 48(denominator). The answer is 0.785. Round it and get 0.79. Hope this helped!
