A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 10cm, and the base has a radius of 6cm. The cooler has 16,956^3cm of water in it. How many cups can be filled from the cooler? Use 3.14 for pie

1 answer

To find out how many cups can be filled from the cooler, we first need to determine the volume of one paper cup, which is shaped like a cone.

The volume \( V \) of a cone can be calculated using the formula:

\[ V = \frac{1}{3} \pi r^2 h \]

where:

  • \( r \) is the radius of the base of the cone,
  • \( h \) is the height of the cone, and
  • \( \pi \) is approximately 3.14.

Given that the height \( h \) of the cup is 10 cm and the radius \( r \) is 6 cm, we can substitute these values into the formula:

\[ V = \frac{1}{3} \times 3.14 \times (6)^2 \times 10 \]

Calculating the radius squared:

\[ (6)^2 = 36 \]

Now substitute that into the volume equation:

\[ V = \frac{1}{3} \times 3.14 \times 36 \times 10 \]

Calculating \( 36 \times 10 \):

\[ 36 \times 10 = 360 \]

Now, substituting back into the equation for volume:

\[ V = \frac{1}{3} \times 3.14 \times 360 \]

Calculating \( 3.14 \times 360 \):

\[ 3.14 \times 360 = 1130.4 \]

Now, dividing by 3:

\[ V = \frac{1130.4}{3} = 376.8 \text{ cm}^3 \]

Now we know the volume of one cup is 376.8 cm³.

Next, we need to find out how many cups can be filled from the cooler which has a total volume of \( 16,956^3 \) cm³.

Calculating \( 16,956^3 \):

\[ 16,956^3 = 16,956 \times 16,956 \times 16,956 \]

Calculating \( 16,956^2 \):

\[ 16,956 \times 16,956 = 287,458,436 \]

Then multiplying by \( 16,956 \):

\[ 287,458,436 \times 16,956 = 4,861,550,940,856 \]

Thus, the cooler has approximately 4,861,550,940,856 cm³ of water.

To find the number of cups that can be filled, divide the total volume of water in the cooler by the volume of one cup:

\[ \text{Number of cups} = \frac{4,861,550,940,856}{376.8} \]

Calculating that gives us:

\[ \text{Number of cups} \approx 12,892,748,433.5 \]

Since we can only fill a whole number of cups, we round down:

Therefore, the number of cups that can be filled from the cooler is approximately \( 12,892,748,433 \) cups.
