The face of a penny has a diameter of 4.2. What is the measurement closest to the circumference of the penny? *
10 points
O 13.2
6.6
13.8
O 5

Work Shown:

pi = 3.14 approximately

d = diameter = 4.2

C = circumference of circle

C = pi*d

C = 3.14*4.2

C = 13.188

C = 13.2

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
