Answer:
Radius = 12 cm
Step-by-step explanation:
Given:
Volume of the cylinder is, 
cm³
Height of the cylinder, 
cm
Let the radius be 
Using the formula for volume of cylinder,
Plug in 3165.12 for 
, 7 for 
and solve for .
Therefore, the radius of the cylinder is nearly 12 cm.

Mabel spends 4 hours editing a 3 minute video. she edits at a constant rate. how long does mabel spend to edit a 9 minute video?
she spends 4 hours on a 3 minute video
so there are 60 minutes in an hour
4 hours with 60 minutes- 4x60=240
so she spent 240 minutes on a 3 minute video
3 divided by 240
3/240= 0.0125
so her constant rate is 0.0125 minutes an hour
so divide 9 minutes by her constant rate
9/0.0125 = 720
so she spends 720 minutes on a 9 minute video.
divide 720 by 60 since there are 60 minutes in an hour
720/60 = 12
so she spends 12 hours on a 9minute video
Answer:
no solutions
Step-by-step explanation:
The lines are parallel since they have the same slope
y = mx+b where m is the slope
They have different y intercepts (b)
The will never intersect so they have no solutions
Answer:
y = -1/3x - 1
Step-by-step explanation:
Let's solve for y.
Step 1: Add -x to both sides.
x+3y+−x=−3+−x
3y=−x−3
Step 2: Divide both sides by 3.
y=-1/3x-1
