Since water piper is a cylinder shape, the equation to calculate the volume of a cylinder is:
Volume = radius* radius * 3.14 * height
volume = 5 * 5 * 3.14 * 7
Volume = 25 * 3.14 * 7
Volume = 25 * 21.98
Volume = 549.5
The volume of water take to fill the pipe is 549.5 cubic centimeter.
A.

b and c.
add 5 to both sides:

subtract 3n from both sides:
Answer:
A.
Step-by-step explanation:
So you would have f(3) = 3 + 
f(3) = 3 + 1
f(3) = 4
Answer:
x = - 1, y = 4
Step-by-step explanation:
A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.
B.
x + 2y = 7
<u>+ 3x - 2y = -11</u>
4x = - 4
x = - 1
x + 2y = 7
-1 + 2y = 7
2y = 8
y = 4
