Danny Henry made a waffle on his six-inch-diameter circular griddle using batter containing a half a cup of flour. Using the same batter, and knowing that all waffles have the same thickness, how many cups of flour would Paul Bunyan need for his 24-foot-diameter circular griddle?
To solve this problem, I need to compare the areas of the two circular griddles and use the fact that the amount of flour is proportional to the area of the waffle. The area of a circle is given by the formula A = pi * r^2, where r is the radius. The radius of Danny's griddle is half of the diameter, so r = 6 / 2 = 3 inches. The radius of Paul's griddle is also half of the diameter, but I need to convert feet to inches first. One foot is 12 inches, so r = 24 * 12 / 2 = 144 inches. Now I can plug in these values into the area formula and simplify. The area of Danny's griddle is A = pi * 3^2 = 9 pi square inches. The area of Paul's griddle is A = pi * 144^2 = 20736 pi square inches. To find the ratio of the areas, I can divide the area of Paul's griddle by the area of Danny's griddle. The ratio of the areas is 20736 pi / 9 pi = 2304. This means that Paul's griddle is 2304 times larger than Danny's griddle in area. Since the amount of flour is proportional to the area of the waffle, I can multiply the amount of flour that Danny used by 2304 to get the amount of flour that Paul needs. Danny used half a cup of flour, so Paul needs 2304 * (1/2) = 1152 cups of flour.
