Q. Suppose the diameter of a circle is 66 units. What is its circumference? \newlineUse 33.1414 for π \pi and enter your answer as a decimal.\newline□\square units
  1. Identify Formula: Identify the formula to calculate the circumference of a circle. The formula for the circumference CC of a circle is C=π⋅dC = \pi \cdot d, where dd is the diameter of the circle.
  2. Plug Diameter: Plug the given diameter into the formula.\newlineThe given diameter dd is 66 units. Using 3.143.14 for π\pi, the formula becomes C=3.14×6C = 3.14 \times 6.
  3. Perform Multiplication: Perform the multiplication to find the circumference. C=3.14×6=18.84C = 3.14 \times 6 = 18.84 units.
