The radius of a circle is 11 centimeters. What is the circle's circumference?
Use 𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
The formula for the circumference of a circle is given by C = 2πr, where r is the radius of the circle.
Given that the radius of the circle is 11 centimeters, we can substitute this value into the formula:
C = 2π(11)
Using the approximation π ≈ 3.14, we can simplify the expression:
C ≈ 2*3.14*11
C ≈ 69.08
Rounding to the nearest hundredth, the circumference of the circle is approximately 69.08 centimeters.
