1. Jun wanted to know how much ice cream he got in one scoop. The radius of a scoop is 2 inches. Find the

volume. Use 3.14 for pi.

What is asked in the problem

The volume of ice cream that Jun got im one scoop.

What are the given facts

r = 2inches

What is the formula to be used

V = 4Pir^3/3

Number Sentence and final answer

V = 4(3.14)(2in)^3/3

V = 100cu.in/3

V = 33.49 cu.in

*The volume of ice cream that Jun’s got in one scoop is 33.49 cubic inches

2. Find the volume of milk chocolate in a glass with a radius of 5cm and height of 10cm.

What is asked in the problem

The volume of milk chocolate

What are the given facts

r = 5cm and h = 10 cm

What is the formula to be used

V = Pir2h

Number Sentence and final answer.

V = 3.14 (5cm)^2 (10cm)

V = 3.14 ( 25sq.cm)(10cm)

V = 785 cu.cm.

* The volume of milk chocolate in the glass is 785 cubic centimeters.

3. Calculate the volume of the pyramid in the picture.

What is the formula to be used

V = lwh/3

Number Sentence and final answer

V = 4m x 4m x 4m/3

V = 64cu.m/3

V = 21.33 cu.m

* The volume of the pyramid in the picture is 21.33 cubic meters.

4. Mike has a large plastic cup that he is going to fill with water. The plastic cup is in the shape of a

cone with a height of 7 inches and a radius of 3 inches as shown. Find the volume of the water in the

plastic cone cup.

What is the formula to be used

V = Pir2h/3

Number Sentence and final answer:

V = 3.14 ( 3in)2 (7in)/3

V = 197.82cu.in/3

V = 65.94 cu.in

* The volume of a largest plastic cup that he is hoing to fill with water is 66.94 cubic inches.
