3/8 + 1 1/4 equals to <u><em>1.625</em></u>
Step-by-step explanation:
Volume of a cylinder is calculated as pi x radius x radius x height
pi is 3.14
so volume = 3.14 x 6 feet x 6 feet x 12 feet = 1356.48 ft3
so the correct answer is C)1,357 ft3
Factor a square root of 14 out of every expression to get:



Thus, the expression is equal to four times the square-root of 14. The second answer is correct.
The answer is (-1,1)
The solution is the point where the two lines cross each other
