Circle Area (By Peeling!)
[b][color=#c51414]Questions for Extension and Application:[/color][/b][br][br][color=#1551b5]1) Was the "triangle" formed truly a triangle? Explain why or why not. [br][/color][br][color=#1551b5]2) What would we need to do to the number of "peels" in order to make the so-called "triangle" formed look[br] more smooth (like a true triangle) vs. a "choppy" triangle? [/color][br][br][color=#1551b5]3) Suppose an above-the-ground circular swimming pool has a radius of 12 feet. What is the area of the exposed surface of the water it contains? [br][br]4) Suppose a circular track (that surrounds grass) has a circumference of 500 feet. If 3 bags of grass seed are needed to be spread out across every 100 square feet of grass in the circular region inside this track, determine how many entire bags of grass seed will be needed to cover the entire area of the circular region surrounded by this track. [br][br]5) Suppose a 12-inch pizza (pizza with diameter = 12 inches) costs $12.00. Suppose a 24-inch pizza costs $24.00. Which pizza is the better buy? Explain why this pizza is the better buy. (Assume both pizzas have the same thickness.) [br][/color]

INTRODUCTION:
[b]This game is played JUST LIKE the old Milton-Bradley game BATTLESHIP. [br]Yet here we'll be playing within the context of the COORDINATE PLANE. [br]The goal is to to SINK ALL 5 of your opponent's ships before he/she sinks all 5 of yours. [/b][br][br][b]When it is YOUR TURN, be sure to state the following: [/b][br][br][b]1) Quadrant Number[br]2) The Ordered Pair[br][br][/b]For example, stating "Quadrant 2: Negative 3 comma 2" indicates the ordered pair (-3, 2). [br]If it's a "MISS", plot a white point on your game board at that location. [br][color=#cc0000]If it's a "HIT", plot a red point on your game board at that location. [br][br][/color]Once you sink one of your opponent's ships, he/she needs to announce this fact to you. [br]When this does happen, use the SEGMENT tool to mark a sunken ship.
