Problem
What is the volume of a soccer ball that has a diameter of $22 \mathrm{~cm}$ ? Approximate pi at 3.14. Round your answer to the nearest tenth. $\mathrm{cm}^{3}$
Solution
Step 1 ：The diameter of the soccer ball is given as 22 cm. The radius of the ball is half of the diameter, so the radius is \(\frac{22}{2} = 11\) cm.
Step 2 ：The volume of a sphere can be calculated using the formula \(\frac{4}{3} \pi r^{3}\), where \(r\) is the radius of the sphere.
Step 3 ：Substitute the values into the formula: \(\frac{4}{3} \times 3.14 \times 11^{3}\).
Step 4 ：The volume of the soccer ball is approximately 5572.453333333333 cubic centimeters.
Step 5 ：Round the volume to the nearest tenth to get the final answer: \(\boxed{5572.5}\) cubic centimeters.
