Answer:
18.9 in.³
Step-by-step explanation:
volume of cone = (1/3)πr²h
volume of cylinder = πr²h
For both the cone and the cylinder,
r = d/2 = 2 in./2 = 1 in.
Cup A:
volume of cone = (1/3)πr²h
= (1/3)(π)(1 in.)²(3 in.)
= 3.1 in.³
Cup B:
volume of cylinder = πr²h
= (π)(1 in.)²(7 in.)
= 22.0 in.³
difference in volumes:
22.0 in.³ - 3.1 in.³ = 18.9 in.³
