Question 6 of 13intermediate🔧 ApplyShort Answer2 marks

Take a tumbler or a bottle. Measure the length of the curved part of the base of glass or bottle and record it.

Correct Answer

To measure the curved part of the base of a tumbler or bottle, use a flexible measuring tape or a thread.

Place the thread along the curved edge of the base, mark the endpoints, then straighten the thread and measure its length using a metre scale.

The circumference of a typical glass tumbler base is approximately 20-30 cm, while a bottle base may be 15-25 cm depending on its size.

Explanation

The chapter explains on Page 9 (Section 5.4) that for measuring curved lines, we can use a flexible measuring tape or a thread. The thread method involves placing the thread along the curved line, marking the endpoints, straightening the thread, and then measuring its length using a metre scale.

Solution Steps

  1. Use a flexible measuring tape or thread to measure the curved surface.

  2. Place the thread along the curved edge of the base.

  3. Mark the endpoints on the thread.

  4. Straighten the thread and measure its length using a metre scale.

  5. Record the measured length.
