Answer 4

The formula for the length of an arc is=
circumference of circle*(theta/360)
or just simply
2pi*r*(theta/360)

r=12
theta=135

Since the answer is asking you to express your answer using pi, you do not need to multiply pi. so then it would simply be
2r(theta/360)

I think you can do it by yourself now with basic multiplication

Answer 5
