Conor has designed a circular shaped sandbox. He will build a circular path around the sandbox as seen in the diagram below. The radius from the center of the sandbox to the edge of the path is twice the length of the radius of the sandbox. The entire project will use approximately 85 ft2 of land.
What is the area, to the nearest tenth, of the path around the sandbox?

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing.
