2.6 The tin has an inner radius of 3.3 cm . Calculate the height (in cm ) of the paint in the tin, if 1 litre \( =1000 \mathrm{~cm}^{3} \). You may use the following formula: Height \( =\frac{\text { Volume }}{3,142 \times \text { (radius }^{2}} \)

To find the height of paint in the tin, we'll use the volume of paint provided (1 liter = 1000 cm³) and the inner radius of the tin (3.3 cm). Plugging these values into the formula, we have: Height = Volume / (3.142 x (radius²)) = 1000 / (3.142 x (3.3)²) ≈ 28.6 cm. So, the height of the paint in the tin is approximately 28.6 cm! When it comes to understanding the importance of measurements, they’ve played a significant role throughout history. Ancient civilizations were the pioneers in inventing units of measure. For example, the Egyptians utilized the cubit for building their monumental structures. Let's just say that without accurate measurement, we might still be trying to figure out how to stack bricks! So, the next time you're calculating something, remember that you’re part of a long tradition of measurement!
