Answer:
(B) 4 cm
Explanation:
Assuming the meatballs are shaped like spheres, we can set up an equation to solve for the radius of each meatball:
Then, solve for "r" by approximating pi to 3.1415 to get r = 1.9997... . Since the diameter is twice the radius, it will be 3.9995... which is approximately 4 cm.
Hope this helps :)
