You are probably familiar with Tetrahedral or Triangular Pyramidal numbers. They are the total number of points we would get from stacking successively larger triangles. See the figure to the right. The points in each level are 1, 3, 6, 10, 15, ... in other words, the triangle numbers. Stacking them, then the Triangular Pyramidal numbers are 1, 4, 10, 20, 35, .... Pyramidal numbers can be made with any shape; for instance... pentagons! Pentagonal Pyramidal numbers are those you get from stacking successively larger pentagons. Pentagon or Pentagonal numbers are 1, 5, 12, 22, 35, ... which gives the first several Pentagonal Pyramidal numbers as 1, 6, 18, 40, 75, .... Designate the nth Pentagonal Pyramidal number as PP. For instance, PP = 18. 1 Evaluate: Σ ΣPP. n =

... Parks will be built adjacent to two circular retention ponds. Each pond has 5 miles in radius. Each park will be covered with grass in the area depicted in light green in the figure below. What is the area of one of the parks? If all sides of each park need to be fenced (e.g. one straight side and the two circular sides bordering each park), what is the length of the fence needed? Describe how you came to your answers. 5. The area of the park: The length of the fence: Edit View Insert Format Tools Table 12pt v Paragraph v MacBook Air 000 000 DD F3 F4 F5 F8 %23
