Answer:

The volume of oil in a barrel is 113.04ft³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

6in = 0.5ft

v = volume

h = height = 4.5ft  - 0.5in = 4ft

π = 3.14

r = radius = 6ft /2 = 3ft

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (3ft)²) * 4ft

v = (3.14 * 9ft²) * 4ft

v = 28.26ft² * 4ft

v = 113.04ft³

The volume of oil in a barrel is 113.04ft³

Michael saves $423 dollars a month for college.
alexandr1967 [171]

Answer:

(a). $20,000

(b). The estimate will be lower than the actual amount.

Step-by-step explanation:

We have been given that Michael saves $423 dollars a month for college.

(a). We know that 1 year equals 12 months.

4 years = 4*12 months = 48 months.

\text{Actual amount saved}=\$423\times 48

Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:

423\approx 400\\\\48\approx 50

\text{Actual amount saved}=\$400\times 50

\text{Actual amount saved}=\$20,000

Therefore, Michael will save approximately $20,000 in 4 years.

(b).

The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.

Therefore, the estimate will be lower than the actual amount.

You start with $.50 at the beginning of the year. This amount doubles every month. How much will you have at the end of the 12th
Doss [256]
Take .50 and multiply it by 2 because it doubled. then multiply that by 6 or 12 to get your answer

NEED HELP ASAP!<br> find the volume of the cylinder
denpristay [2]

Answer:

V = 314.2 ft^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h    r is the radius (5) and h is the height (4)

Using the pi button for pi

V = pi (5^2) (4)

V =314.1592654

Rounding to the nearest tenth

V = 314.2 ft^3
