  3. 5/12/2014 10-2 B Volume of Cylinders

  4. Key Concept

  5. Volume of a Cylinder • Label the BASE and HEIGHT of the cylinder below: Height of the Cylinder! Base of the Cylinder!

  6. Example 1 Find the volume of the cylinder. Use 3.14 for . Round to the nearest tenth. V = r2h V ≈ 3.14(4)2(5) V ≈ 251.2 The volume is about 251.2 cubic centimeters.

  7. Example 2 The cylinder-shaped vase has a height of 12 inches and a diameter of 4 inches. What is the volume of the vase? Use 3.14 for . Round to the nearest tenth.

  8. V = r2h V ≈ 3.14(2)2(12) V ≈ 150.7 The vase has a volume of about 150.7 cubic inches.

  9. Ex.3 Area of a Circle V = Bh = r2• h = (8ft)2 • (9ft) = 64ft2 • (9ft) = 576ft3 = 1809.6ft3 16ft 9ft
