The diameter of a circle with a circumference of 4.5 inches can be calculated using the formula C = πd. Rearranging this formula to solve for the diameter (d), we get d = C/π. Substituting the given circumference, d = 4.5/π, which approximately equals 1.43 inches.
FAQs & Answers
- What is the formula to find the diameter from circumference? The diameter can be found using the formula d = C/π, where C is the circumference.
- How do you calculate the circumference of a circle? The circumference can be calculated using the formula C = πd or C = 2πr, where r is the radius.
- What is the relationship between diameter and circumference? The diameter is directly related to the circumference through the relationship C = πd, indicating that circumference is proportional to the diameter.
- Can you calculate the diameter without knowing the radius? Yes, as long as you know the circumference, you can calculate the diameter using the formula d = C/π.
