Question

If the circumference of a round barn is 56 meters, what is the diameter of the barn to the nearest whole meter ? Use 3.14 pi

Answer 1

To calculate a circle's diameter from its circumference, you divide the circumference by the constant pi. So 56 divided by 3.14, which equals 17.83439490445859872611464968152866242. Round that to the nearest whole meter, you get 18 meters. Therefore, the diameter of the barn is 18 meters.
