Lesson 9.4 Concept: Find the volume of a circular cylinder. Guidelines: Volume = area of base • height v = πr2 • h v = 3.14 • 7 • 7 • 5 v = 3.14 • 49 • 5 v = 769.3 ft3 14 cm 5 cm
Find the height of the cylinder. substitute v = πr2 • h Volume = 1,130.4 ft2 6’ 1,130.4 = 3.14 • 6 • 6 • h h 1,130.4 = 113.04 h 113.04 113.04 h = 10
