Question

Carmen is packing moisturizing bath powder into spherical molds. She has enough powder to fill about 12 spherical molds with a diameter of 4 cm. How many spherical molds with a diameter of 5 cm could she fill with the same amount of powder? Show your work.​

Answer 1

8

Explanation:

+, the overall volume of moisturising bath powder is: V=4/3 π×R³×12 = 4/3 π×2³×12=128π(cm³)

=>the number of spherical molds with a diameter of 5cm she could fill with the same amount of powder is: N=V/(4/3 π×R'³)= 8
