The volume of the cup is 20 cubic inches.
Explanation:
Given that the cup is in the hemispherical shape.
Radius of the cup = 2.125 inches
Volume of the cup = (2/3) π(r x r x r)
= (2/3) (3.14) (2.125 x 2.125 x 2.125)
= (2/3) (3.14) ( 9.59)
= (2/3) (30.13)
= 20 cubic inches
The volume of the cup is 20 cubic inches.
