The diameter of a circle can be found using the circumference formula: C = πd. For a 6 cm circumference, the formula is rearranged to d = C/π. This gives a diameter of approximately 1.91 cm.
FAQs & Answers
- What formula is used to find the diameter from circumference? The diameter can be found using the formula d = C/π, where C is the circumference.
- What is the relationship between diameter and circumference? The circumference of a circle is proportional to its diameter, expressed as C = πd.
- How do you measure the diameter of a circle without a ruler? You can estimate the diameter by measuring the circumference and dividing by π.
- Why is π important in circle calculations? π (Pi) is a mathematical constant that represents the ratio of a circle's circumference to its diameter, crucial in circle-related calculations.
