Question 978654
volume of cylinder(V) = pi * r^2 * h where r is radius and h is height
V = (3.14) * 3^2 * 6 = 169.56 cm^3
note using pi = 3.14
now we divide the volume by 12, 169.56 / 12 = 14.13 cm^3
each of the 12 spheres has a volume of 14.13 cm^3
volume of a sphere is (4/3)*pi*r^3
14.13 = (4/3) * (3.14) * r^3
multiply both sides of = by 3
42.39 = 12.56 * r^3
divide both sides of = by 12.56
r^3 = 3.367834395
r = 1.498937677  approx 1.5
diameter = 2 * 1.5 = 3 cm
the answer is b
