Let’s Try These: 3 cm 24 cm 13 m
Practice Time: • 11- 7 Practice • 1, 3, 5, 6, 8 • Write an EQUATION for each • Problems not finished need to be finished as homework! • When these are done do 2 and 4 • REMEMBER: • Area of circle = π r2 • Circumference = 2 πr • Solve to find the value for r and then find the volume of the sphere
