Monday Math Madness • Why does a flamingo lift up one leg? • Why do birds fly south in the winter? • What's an insect's favorite sport?
Do Now Divide 1.) 3.45 ÷ 1.5 2.) 4.22 ÷ 2 3.) 150.27 ÷ 3
Volume of a Cylinder • Label the BASE and HEIGHT of the cylinder below: Height of the Cylinder! Base of the Cylinder!
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.
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.
V = r2h V ≈ 3.14(2)2(12) V ≈ 150.7 The vase has a volume of about 150.7 cubic inches.
Ex.3 Area of a Circle V = Bh = r2• h = (8ft)2 • (9ft) = 64ft2 • (9ft) = 576ft3 = 1809.6ft3 16ft 9ft
