The radius of the tennis ball is 3.5 cm (half of the diameter) and the radius of the football is 11 cm.
The formula for the volume of a sphere is V = (4/3)πr^3.
For the tennis ball:
V = (4/3)π(3.5^3)
V ≈ 179.6 cm^3
For the football:
V = (4/3)π(11^3)
V ≈ 5575.3 cm^3
The difference between the two volumes is:
5575.3 - 179.6 ≈ 5395.7 cm^3
Rounding to the nearest centimetre, the difference is approximately 5396 cm^3.
Round off to the nearest centimetre the diameter of a tennis ball is 7 cm and diameter of a football is 22 cm. Complete the calculation to find the difference between the two volume to the nearest centimetre
