Volume of a Cylinder Worksheet Solutions for Grade 8

To calculate the total space occupied by a 3D object with a circular base and straight sides, use the formula: π × r² × h, where r is the radius of the base, and h is the height. This formula helps determine the three-dimensional space inside objects like pipes, tanks, and more. Be sure to square the radius before multiplying by the height to get accurate results.

For practice, students should work through problems involving different values for radius and height, adjusting the measurements in the formula to calculate the total capacity. For example, if the radius is 4 cm and the height is 10 cm, the calculated volume will be π × 16 × 10, or 160π cm³. Always remember to express your answer in cubic units.

With these exercises, you’ll gain a clearer understanding of geometric calculations involving circular bases. Keep in mind that practicing with varying measurements and conditions will solidify your understanding of these mathematical principles. Use the formulas correctly and apply them to solve a wide range of problems effectively.
