1.I have a triangular graden in my backyard.One side is 4 meters and another side 6 meter.The angle that is formed by these two sides is 72 degreees.What is the area of the garden?
2.Jill's car tires are spinning at a rate of 120 revolutions per minute.If her car tires'radii are each 14 inches,how many yards does she travel in 5 minutes?
3.The figure shows a circle with center Y.Assume minor arc PO=minor arc EK.prove that line PO is congruent to line EK.

1.½ x 4 x 6 x sin72° = 12 x sin72° ≈ 11.41 m³
2.轮胎半径R = 14英寸 = 14/36 = 7/18 码
2π x 7/18 x 120 x 5 = 1400π/3 ≈ 466.67 码
3.连接PY、OY、EY、KY
扇形PYO的面积 = ½ x 弧PO x 圆半径R
扇形EYK的面积 = ½ x 弧EK x 圆半径R
∵ 劣弧PO = 劣弧EK
∴ 扇形PYO的面积 = 扇形EYK的面积
又∵ 扇形PYO的面积 = ∠PYO x πR² / 360°
扇形EYK的面积 = ∠EYK x πR² / 360°
∴ ∠PYO = ∠EYK
在△PYO和△EYK中,
PY = EY
∠PYO = ∠EYK
OY = KY
∴ △PYO ≌ △EYK
∴ PO = EK

1. 我的后院有一个三角形的花园。一边是4米，另一边是6米，这两边形成的角是72度。这个花园的面积是多少？
2. 吉尔的车轮胎每分钟转120圈。如果她每个车胎都是14英寸，那么她五分钟行驶了多少码？（注：1码=3英尺，1英尺=12英寸）
3. 下图是一个圆，Y点为中心。假设劣弧PO=劣弧EK，证明直线PO=直线EK。
