Rounding Errors

After calculating, some students round off their answers without considering the number of decimal places required. This can lead to slight but noticeable errors in the final answer.

Misunderstanding of Pi (π)

Some students incorrectly use 3.14 as the value of pi for calculations. The correct value should be used, as it's a constant that represents the ratio of a circle's circumference to its diameter.

Forgetting to Cube the Radius

When calculating the volume of a sphere, the radius should be cubed (raised to the power of 3). Forgetting this step can lead to incorrect results, as the formula is V = 4/3 * π * r³.

Common Pitfall - Incorrect Radius Measurement

Often, students mistakenly use the diameter instead of the radius when calculating the volume of a sphere. The formula requires the radius, so accurate measurement is crucial.

Using the Formula for Cylinders or Cubes

Students may confuse the volume formulas for spheres with those for other 3D shapes. Using the wrong formula can result in significant errors, as the volume of a sphere is calculated differently.
