Mr. Arnold needs to paint 1,600 square feet of his house. Each gallon of paint will cover 250 square feet. So you would divide 1600 by 250 to figure out how many cans he needs. the answer is 6.4. Then it says that he had one left over from the last time he painted his house. So he only needs 5.4 gallons now. The end question is whether or not Mr. Arnold needs more than 5 gallons and the answer is yes. Because he needs 5.4 gallons. .4 gallons more than 5.
The answer is C. when you have questions like these, its best to plug in an easy number and test it out.
Say the original radius was 2. That means the area of that sprinkler was 12.56 (if you use the formula Pi(radius)squared.
a number 3 times bigger then 2, is 6. (2 times 3 = 6) There fore, following the same formula as before, you plug that number in and get 113.04 as the area of the new sprinkler.
113.04 divided by 12.56 is 9
