If the diameter of a circle is 19.3, what is the circumference?
vlabodo [156]

Answer:

60.6

Step-by-step explanation:

The formula for finding the circumference of a circle is C = 2πr

C is circumference, π is pi (we'll just us 3.14 here), and r is radius.

The radius is found by dividing the diameter in half.

19.3/2=9.65

So the equation should look like this:

C = 2(3.14)(9.65)

C = 60.602

C = 60.6
