Questions: How much ice cream 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. (1 point)

Solution Steps

The volume \( V \) of a sphere is given by the formula: \[ V = \frac{4}{3} \pi r^3 \] where \( r \) is the radius of the sphere.

Given:

• Radius \( r = 3 \, \text{cm} \)
• Approximation for \( \pi = 3.14 \)

Substitute these values into the formula: \[ V = \frac{4}{3} \times 3.14 \times (3)^3 \]

First, calculate \( (3)^3 \): \[ (3)^3 = 27 \]

Now, substitute this back into the equation: \[ V = \frac{4}{3} \times 3.14 \times 27 \]

Calculate the multiplication: \[ V = \frac{4}{3} \times 84.78 \]

\[ V = 113.04 \, \text{cm}^3 \]

The volume \( 113.04 \, \text{cm}^3 \) rounded to the nearest whole number is \( 113 \, \text{cm}^3 \).
