1: Find the parametric equations of a circle with a radius of 7.5 where you start at point (-7.5,0) at t=0 and you travel clockwise with a period of 6. Note: t is in radians.

2: Find the parametric equations of a circle with a radius of 3.5 where you start at point (-3.5,0) at u=0 and you travel counterclockwise with a period of 10. Note: u is in radians.

3: The Conroys had to hire a surveyor to determine for sure exactly what the boundary of their property was. The surveyor walked around the edge of their property starting from point A and moving N 32E a distance of 543 feet to point B. Next, she moved N53E a distance of 395 feet; to point C. Next, she walked S7W a distance of 1627 feet; to point D. Finally, she returned to the starting point. That path enclosed all of Conroy's property. What distance must she walk to return to the starting point=? What heading does she walk from the fourth point to return to the starting point? N =? What is the acreage of this plot of land? area = ? Your answer should be accurate to 3 decimal places. Notes: * 1 acre = 4840 yd * 1 acre = 43,560 ft * an angle like N 20 E means 20 degrees east of north.
