  1. Wednesday April 2, 2014Bell Ringer: 15 in Find the Volume of the figure below: 8 in 9 in

  2. What We are Learning Today: • To find the Volume of Spheres and Hemispheres

  3. What is a Sphere? A Hemisphere? • Sphere: A three-dimensional closed surface consisting of all points that are a given distance from a center. • Hemisphere: Half of a sphere • Volume =

  4. Volume of a Sphere: • Volume of Sphere = • Volume of a Hemisphere =

  5. Let’s Try These: 3 cm 24 cm 13 m

  6. 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
