C Correct answer
Explanation

Volume = (4/3) * pi * r^3 = (4/3) * pi. Thus r^3 = 1, so r = 1 cm. Converting to meters, 1 cm = 0.01 m.

AI explanation

The volume of a sphere is given by the formula V = (4/3)πr^3. Setting (4/3)πr^3 equal to (4/3)π gives r^3 = 1, so the radius is 1 cm. Converting this value to meters results in 0.01 m. The radius is 0.01 m.
