Answer:
R = 4cm
Step-by-step explanation:
V = π(R)²h = 480π
Divide by π
(R)²h = 480
Substitute h with 30
30*(R)² = 480
Divide by 30
(R)² = 16
Square root
R = 4cm
We do not accept R= -4 because it's a length, so it must be positive.

Step-by-step explanation:
A linear function is a straight line so all you have to do is find a slope and a y-intercept
Slope = (7 + 2)/(-18 + 4) = 9/-14= - 9/14
Answer:
Step-by-step explanation:
1/5* 1/4 * 1/3
I think it is the second one
one fifth
one fourth
one third
I think that using the elimination method is the best, because it is the only method that I use when solving these types of equation. For example, for these two equations, you need to multiply one of the equations by a certain number so that you'd be able to find x and y. The elimination method is the method that tells you to do that. It is also the easiest method.
