Answer:
48 inches
Step-by-step explanation:
Put the value of the variable where the variable is in the expression and do the arithmetic.
P = 8s
P = 8(6 in)
P = 48 in
The perimeter of the octagon is 48 inches.
<em><u>Explanation</u></em><em> </em><em>:</em>
The line DF is parallel to OB, therefore Angle x = Angle y.
( because, they for corresponding angle pair which are equal. )
And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence
Permutation:
5! = 5 * 4 * 3 * 2 * 1 = 120
