Apie is cut into 6 pieces if the diameter of the pie is 10 inches what is the approximate arc length of one slice of pie?

pie = symbol
a- 10pie / 3
b- pie
c- 5pie / 6
d- 5pie / 3

We are assuming the 6 pieces are equal.

Let the radius be R=5 in. 

The circumference of the pie is given by C=2πR=2π*5 (in) = 10π (in)

The pie is cut into 6 pieces means that the circumference is also divided into 6 arcs of equal length = 10π/6 (in)= 5π/3 (in)

 D- 5pie / 3
