The volume of a cylinder is found with V=pi*r^2*h
The radius is 9 (18/2)
We can plug in what we know to find the volume
V=pi*9^2*3
V=pi*81*3
V=243*pi
Hope this helps
1/3 times 1/5 equals 1/15. That is already simplified :).
X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
Answer:
A. x=0
Step-by-step explanation:
x+20+10x=20+9x
cancel equal terms
x+10x+9x
add x to 10x
11x=9x
move variable to left
11x-9x=0
subtract 11x to 9x
2x=0
divide Both sides by 2
x=0
