Decision:
1. Find the radius of the ball. It is equal to half the diameter: r = d / 2.
r = 220/2 = 110 (mm).
2. Find the volume of the ball. It is found by the formula: V = (4/3) * π * r3, where n = 3.14.
V = (4/3) * 3.14 * 1103 = (4 * 3.14 * 133100) / 3 = 16717360/3 = 5572453.33 mm3.
3. Let’s convert mm3 to cm3 and dm3. In one cm3 1000 mm3. In one dm3 1000 cm3 and 1,000,000 mm3.
5572453.33 mm3 = 5572.45 cm3 = 5.57 dm3.
Answer: 5572453.33 mm3, or 5572.45 cm3, or 5.57 dm3.
