Question

If the diameter of a baseball is 2.94", what is the radius, the circumference and the surface area volum?

Answer 1

Learn your formulas for round objects

radius = diameter/2

circumference = d(pi) or 2(pi)r

surface area = 4 (pi)r^2

volume = 4/3(pi)r^3

For your problem, since the diameter = 2.94, the radius = 1.47"  plug this into the formulas.
