It is estimated that the value of a new car is reduced 30% after one year of ownership. find the value after one year of a car that cost $21,600 new.

The value of a car  after one year is $15,120.

The value of a car depreciates by 30%. The equation that can be used to determine the value of the car after one year is:

Where:

$21,600 ( 1 - 0.30)

$21,600 x 0.70 = $15,120

$15,120

Step-by-step explanation:

30% of the value is lost the first year, leaving 70%.

So we multiply $21,600 by 0.70, obtaining   $15,120.  This is the value after one year.

Step-by-step explanation:

Volume of a cylinder is given by cross sectional area multiplied by height hence

V=Ah

Since the cross sectional area of

Substituting the formula for A into formula for volume then

Substituting 8ft for r and 20 ft for h then

Rounded off to the nearest tenths, the volume is equivalent to
