Answer:
V = πr²(h/3)
Step-by-step explanation:
83.74 = πr²(5/3)
R = 4.00 in
Diamater = 2r = 2 x 4.00 = 8 inches
Answer:
315
425 + -115 = 315 feet
Step-by-step explanation:
Answer:
The x-coordinate of the solution to this system of equations is 3
Step-by-step explanation:
Given the system of equations:
....[1]
....[2]
Add equation [1] and [2] we have;

Simplify:

Divide both sides by 3 we have;
x = 3
Substitute in [1] we have;
3+y = 3
⇒y = 0
Solution for the given system of equation is= (3, 0)
Therefore, the x-coordinate of the solution to this system of equations is 3
6x=120-5y -> x=20-5/6*y -> 7(20-5/6*y) + 11y =202 -> 140-35/6*y + 11y = 202 -> 140+31/6*y=202 -> 31/6*y = 62 -> y = 12.
