Question
The circumference of a circular painting is 47.1 feet. What is the radius of the painting? Use 3.14 for π and do not round your answer.
Solution
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.
Given that the circumference (C) is 47.1 feet, we can rearrange the formula to solve for the radius (r):
r = C / (2π)
Substituting the given values:
r = 47.1 / (2 * 3.14)
r = 47.1 / 6.28
r = 7.5 feet
So, the radius of the painting is 7.5 feet.
