The formula for area of a circle is A=rsquared*3.14. Divide 5.5/2 to get 2.75. Mulitply 2.75 times 2.75 to get approximately 7.56. Then, multiply that times 3.14 to get approximately 23.74.
Answer=23.74 yards
You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
Answer:
39.16% probability of selecting three Democrats and three Republicans
