The diameter of a football is measured to be 60 cm, correct to the nearest 0.5 cm. Find the range of the actual diameter of the football.
Solution
Hints:
59.75 cm to 60.25 cm
The measurement is to the nearest 0.5 cm, so the error is \\pm 0.25 \\text{ cm}. Range = 60 - 0.25 \\text{ to } 60 + 0.25 = 59.75 \\text{ cm to } 60.25 \\text{ cm}.
