The answer is:
Square root of 77
—————————
22
You need to rationalize the denominator meaning that you have to get rid of the square root signs in denominator
To get rationalize the denominator you need to multiply both sides by square root of 11
(Square root of 7)(square root of 11)
——————————————————
2(square root of 11)^2
When squaring a square root it makes the square root “go away”
(Square root of 77)
——————————
2(square root of 11^2 or 122) = 2(11)
So:
The answer is
square root of 77
—————————
22

The answer to your question is G
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
Answer:
(x,y)=(44,-6)
