give me the radius of a circle from the circumference being 94.2 centimeters
Answers
GPT 3.5
The formula to find the circumference (C) of a circle is C = 2πr, where r is the radius.
To find the radius (r) from the given circumference (C), we can rearrange the formula as follows:
r = C / (2π)
Substituting the given circumference (C = 94.2 cm) into the formula:
r = 94.2 cm / (2π)
Using a calculator to approximate π as 3.14:
r ≈ 94.2 cm / (2 × 3.14)
r ≈ 94.2 cm / 6.28
r ≈ 15 cm
Therefore, the radius of the circle is approximately 15 centimeters.
