What is the approximate circumference of a circle that has a radius of 63? Use 3.14 for pi and express your answer to the hundredths place.
The formula for the circumference of a circle is C = 2πr, where r is the radius and π is pi.
Substitute in the given values:
C = 2 * 3.14 * 63
Simplify:
C = 395.64
Therefore, the approximate circumference of the circle is 395.64 units (rounded to the hundredths place).
