How many feet of tile will they need? many feet of tile will they need? C= d (use pi = 22/7). They will need C= d (use pi = 22/7). They will need 44 of tiles. (22 x 14 2 ) = of tiles. (22 x 14 2 ) =

19 JOKE THE ROUNDEST KNIGHT AT King Arthurs round table was Sir Cumference. He acquired his size from too much pi. THE ROUNDEST KNIGHT AT King Arthurs round table was Sir Cumference. He acquired his size from too much pi.

20 Area of a Square A= S If S = 2, A = 4 square inches If S = 3, A = 9 square (3 x 3) (3 x 3)

21 Word Problems If the Adams new bathroom If the Adams new bathroom is 8 by 8, how many 12 is 8 by 8, how many 12 tiles will they need to tile the tiles will they need to tile the bathroom? bathroom? A = S squared, A = 8 squared, A = 64 square feet or 64 tiles.

22 Area of a Rectangle A = LW (length times width) A = LW (length times width) If L = 4 and W = 2, then If L = 4 and W = 2, then A = 8 square A = 8 square If L = 3 and W = 1, If L = 3 and W = 1, Then A = 3 square inches Then A = 3 square inches

23 Word Problems If the Bells new patio is 20 If the Bells new patio is 20 by 10, how many 12 tiles by 10, how many 12 tiles will they need to cover the will they need to cover the patio? A = LW (20 x 10 = 200) patio? A = LW (20 x 10 = 200) They will need 200 square feet or They will need 200 square feet or 200 tiles. 200 tiles.

24 Area of a Triangle A = 1/2BH (base x height) A = 1/2BH (base x height) If B = 8 and H = 4, If B = 8 and H = 4, then A = ½ of 32 then A = ½ of 32 A = 16 square inches A = 16 square inches

31 Word Problem The Garden-Gro Shop has several different sizes of planter boxes. The Garden-Gro Shop has several different sizes of planter boxes. Some are square, some rectangular, and some are round. We need to find the amount of potting soil we will need for each kind and size purchased. Some are square, some rectangular, and some are round. We need to find the amount of potting soil we will need for each kind and size purchased.

32 Planters (cont.) V=S If the sides of V=S If the sides of this cube-shaped planter box are this cube-shaped planter box are 2, then V=2 x 2 x 2 = 8 cubic feet. 2, then V=2 x 2 x 2 = 8 cubic feet.

33 Planters (cont.) If this rectangular flower box If this rectangular flower box is 3 x 2 x 2, then V=LWH or is 3 x 2 x 2, then V=LWH or 3 x 2 x 2= 12 cubic feet. 3 x 2 x 2= 12 cubic feet.

34 Planters (cont.) If this circular flower pot has a If this circular flower pot has a radius of 7 and is 10 high, then radius of 7 and is 10 high, then V= r h. V= r h. V= 22/7 x 7 x 10 V= 22/7 x 49 x 10 ( 22/7 x 49 7 ) V = 22 x 7 x 10 = 154 x 10 = 1,540 cubic of potting soil needed.
