Answer:
7/3
Step-by-step explanation:
Keep Change Flip -KCF (not to be confused with kfc )
7/8 x 8/3
Keep Change Flip in other words, keep the <u>first fraction</u> change from <u>division to multiplication</u> (since multiplication is the opposite of division) and flip the <u>second fraction</u>
7 more boxes because if you take 16 away from 100 you get 84 then you divide that by 12 and get 7 boxes
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
