The gcf of 8 & 18 is 2 because no other number can go into both except 2
the lcm is 72 because thats the lowest number that both of them can be multiplied to get
The surface area of a cylinder is the sum of the top + bottom + body, right?
The top and the bottom are circles with the same radius 3.5 . And we know that the area of a circle is r^2pi, (don't forget we have 2 circle, so, the answer must be multiplied by 2)
Now, the body: the body is just a rectangular with the width is the height of the cylinder and the length is the circumference of the circle.
The circumference = 2 r pi
the height is given
All you need to do is to calculate them and add them up. You need to work out to get the answer.
Answer:
Step-by-step explanation:
Divide both sides by R.
Switch sides.
Take the square root of both sides.
Answer:
I think the answer is... C. No Solution because if you plug in those points for x & y, it has no solution... It is false... so yeah... I'm really really sorry if I'm wrong...
Step-by-step explanation:
x -2y = 4 - 3x + 6y = 12
-2 - 2(4) = 4 - 3(-2) + 6(4) = 12
-2 - 8 = 4 6 + 24 = 12
-10 = 4 30 = 12
x -2y = 4 - 3x + 6y = 12
0 - 2(-2) = 4 - 3(0) + 6(-2) = 12
0 + 4 = 4 0 - 12 = 12
4 = 4 - 12 = 12
