The circumference of a circular painting is 12.56 feet. What is the diameter of the painting? Use 3.14 for pie and do not round your answer.

Answer 1

The circumference, C, (or the distance around) of a circle is calculated by:

C = ¶ • d where ¶ = 3.14 and d represents the diameter of the circle

For this problem, the circumference C is 12.56 feet:

12.56 = 3.14 • d

12.56/3.14 = d

4 feet = d

The diameter is 4 feet.
