volume of cylinders - item 20987 question 1 of 7
you have a can that is in the shape of a cylinder. it has a volume of about 1,728 cubic centimeters. the height of the can is 22 centimeters. what is the approximate length of the radius? use 3.14 for pi.

approximately the radius is 5 cm

Step-by-step explanation:

The formula for Volume of a Cylinder is shown below:

Volume of a Cylinder:

Where

V is the volume

r is the radius

h is the height

We know

V = 1728

h = 22

We substitute and find r:

So we can that approximately the radius is 5 cm

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
