Question
In the circus, a monkey rides a unicycle with a wheel that has a radius of 9 inches. What is the wheel's circumference?Use 3.14 for 𝜋. If necessary, round your answer to the nearest hundredth.
Solution
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
Step 1: Identify the radius. In this case, the radius of the wheel is 9 inches.
Step 2: Substitute the radius into the formula. C = 2π(9)
Step 3: Calculate the circumference. C = 2 * 3.14 * 9 = 56.52 inches.
So, the circumference of the wheel is approximately 56.52 inches.
