the main trunk of a tree is in the shape of a cylinder. The distance around its cross section is 47.1cm and its height is 0.7m. What is the radius of the cross section? I know i have the height and circumference, would i divide the circumference by 4 to get the radius? how would i show my work? plz help! thx.

  1. The radius has nothing to do with the height. It equals (circumference)/(2 pi)

    What they call the "distance around the cross section" is the circumference
