A cup shaped like a hemisphere has a radius of approximately 2.125 inches. Which of the following is the best estimate of the volume of the cup?

The volume of the cup is 20 cubic inches.

Step-by-step 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.
