The formula S=P/n gives the formula for the side length s of a regular polygon with n sides and perimeter P. A regular octagon has 8 equal sides.What is the side length of a regular octagon with a perimeter of 25.6 in.?

Answers

You just plug your numbers into the formula S=P/N

P = 25.6
N = 8

So P/N is 25.6/8 = 3.2

S (or side length) = 3.2

Select the explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 ak = 6 • 3k – 1
ak = 3 • 6k – 1
ak = 6 • 3k
ak = 3 • 6k
