This is a 9in diameter pie, find the arc length of the crust of the pumpkin pie slice

I uploaded the answer to a file hosting. Here's link:

diameter is the whole length across, the radius is half. the radius or length of one side of the pie is 4.5 in

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
