Find the volumes of cylinders. Main Idea/Vocabulary

Key Concept

Find the volume of the cylinder. Round to the nearest tenth. Volume of a Cylinder Find the volume of the cylinder. Round to the nearest tenth. V = r 2h Volume of a cylinder V = (5.5)2(9) Replace r with 5.5 and h with 9. Use a calculator. ENTER 2nd × [] 5.5 x2 855.2985999 9 Answer: The volume is about 855.3 cubic centimeters. Example 1

Find the volume of the cylinder. Round to the nearest tenth. A. 56.5 cm3 B. 169.6 cm3 C. 339.3 cm3 D. 3197.8 cm3 Example 1 CYP

SOUP How much soup can the can hold? V = r 2h Volume of a cylinder V = (1)2(4) Replace r with 1 and h with 4. V ≈ 12.57 Simplify. Answer: It can hold about 12.57 cubic inches of soup. Example 2

JUICE How much juice can this can hold? A. 2,261.9 cm3 B. 942.5 cm3 C. 188.5 cm3 D. 60 cm3 Example 2 CYP
