A snow cone is a tasty treat with flavored ice and a spherical bubble gum ball at the bottom.

anonymous · Answer

The radius of the cone is 1.5 inches, and its height is 3 inches. If the diameter of the bubble gum ball is 0.5 inches, what is the closest approximation of the volume of the cone that can be filled with flavored ice?

 21.21 in3

 0.07 in3

 7.00 in3

 7.07 in3

campbell_st · Answer

well find the volume of the cone

$$V = \frac{1}{3} \pi r^2 h$$

and then subtract the volume of the sphere

$$V = \frac{4}{3} \pi r^3$$

you have been given all the necessary measurements so substitute to find the volumes then subtract for the approximation.
