What is diameter if circumference 42?

Answer 1

The diameter of a circle can be found using the formula ( C = \pi d ), where ( C ) is the circumference and ( d ) is the diameter. Given that the circumference is 42, you can rearrange the formula to find the diameter: ( d = \frac{C}{\pi} ). Thus, ( d = \frac{42}{\pi} \approx 13.38 ) (using ( \pi \approx 3.14 )). Therefore, the diameter is approximately 13.38 units.
