Q1. What is the method for calculating the circumference of a circle using a measuring tape?
Ans. 
To calculate the circumference of a circle, measure its diameter with a tape and multiply by π (pi).
• Use a flexible measuring tape to measure the diameter of the circle directly across its center.

• Ensure the tape is straight and not sagging for an accurate measurement.

• Once you have the diameter (d), use the formula: Circumference (C) = π × d.

• For example, if the diameter is 10 cm, then C = π × 10 cm ≈ 31.42 cm.
