9. Can you answer this? Circles in Real life You are building a circular pen for your dog that has a diameter of 40 feet. You want to tile it with tiles that measure 1 ft x 1 ft. Each tile costs $3.00. You also want to build a fence around the pen. The fence is sold in 4 foot pieces and cost $80.00 per piece. How much money will you have to spend? (Show all your work) (1 pt)How many tiles will you need? ___________ (1 pt)How much $ for tiles? ______________ (1 pt)How many pieces of fence will you need? __________ (1 pt)How much $ for Fence? ______________ (4 pts)How much all together? ______________ 1256 tiles 1256 x $3.00 = $3,768 125.6 feet of fence ÷ 4 ft pieces = 31.4 pieces of fence = 32 pieces 32 pieces x $80.00 = $2,560 $2,560 for fence + $3,768 = $6,328
