How much icecream is in a spherical scoop of ice cream with a radius of 3 cm? use 3.14 as an approximation for pi. Round your answer to the nearest whole number

To find the volume of a spherical scoop of ice cream, we can use the formula for the volume of a sphere:

\[ V = \frac{4}{3} \pi r^3 \]

where \( r \) is the radius of the sphere. In this case, the radius \( r \) is 3 cm.

Using \( \pi \approx 3.14 \):

  1. Calculate \( r^3 \): \[ r^3 = 3^3 = 27 \]

  2. Substitute \( r^3 \) and \( \pi \) into the volume formula: \[ V = \frac{4}{3} \times 3.14 \times 27 \]

  3. Calculate \( \frac{4}{3} \times 3.14 \): \[ \frac{4}{3} \times 3.14 \approx 4.1867 \]

  4. Now calculate the volume: \[ V \approx 4.1867 \times 27 \]

  5. Multiply: \[ V \approx 113.04 \]

Now, round this to the nearest whole number:

\[ V \approx 113 \]

Therefore, the volume of the spherical scoop of ice cream is approximately 113 cubic centimeters.
