Find the volume of this perfume bottle: Hint: V= pi x r^2 x h (Use 3.14 for pi).

* up and down it measures to 12.4 cm and side to side it measures to 6.2 cm

1 answer

To find the volume of the perfume bottle, we can use the formula for the volume of a cylinder:

\[ V = \pi \times r^2 \times h \]

where:

  • \( \pi \) is approximately 3.14,
  • \( r \) is the radius,
  • \( h \) is the height.

From the dimensions given:

  • The height \( h \) of the bottle is 12.4 cm.
  • The width (side to side) measures 6.2 cm. Since this dimension is the diameter of the circular base, we can find the radius \( r \) by dividing the diameter by 2:

\[ r = \frac{6.2}{2} = 3.1 , \text{cm} \]

Now we can substitute the values into the volume formula:

\[ V = 3.14 \times (3.1)^2 \times 12.4 \]

First, calculate \( (3.1)^2 \):

\[ (3.1)^2 = 9.61 \]

Now, substitute that back into the volume formula:

\[ V = 3.14 \times 9.61 \times 12.4 \]

Now, calculate \( 3.14 \times 9.61 \):

\[ 3.14 \times 9.61 \approx 30.1584 \]

Now multiply this by the height \( h \):

\[ V \approx 30.1584 \times 12.4 \]

Calculating that gives:

\[ V \approx 373.96208 , \text{cm}^3 \]

Rounding to two decimal places, the volume of the perfume bottle is approximately:

\[ V \approx 373.96 , \text{cm}^3 \]
