radius = half the diameter ------> 16/2 = 8
pi = 3.14
64*3.14 = 201
If I understood the task, then here are the answers: 1/2=2/4 or 0.5=1/2
Find the total surface.area of a regular pyramid with a square base if each edge of the bars measures 16. inches the slant height of a side is 17 inches and the altitude is 15 inches the perimeter of the bars is 4s since it is a square p=4(16)=64 inches the area of the base is s2 B=16 2 =256 inches 2 t.s.a.=1/2(64)(17)+256 =544+256 =800 inches2
This is not a full question. If you were given the amount at the begining of 1970 (we'll call it x) and the amount at the end of 1980 (we'll call it y), we should solve them accordingly:
y-x=? (calling the answer a)
a/y=%(not answer yet, call this b)
b+100=answer
