The circumference of a wheel is 62.83 centimeters. What is the diameter of the wheel?

Select the correct answer from each drop-down menu. Rewrite the formula for area of a circle to find the radius of a circle. The area of a circle \( (A) \) is given by the formula \( A=\pi r^{2} \) where \( r \) is the circle's radius. The formula to find \( r \) is \( A=54 \) centimeters \( { }^{2} \) and \( \pi=\frac{22}{7}, r \) is \( \quad \therefore \) centimeters.
