Hello,

I have a trig worksheet to do and i am stuck on question 3 and 6.

Question 3 states: Through how many radians does a wheel of radius one travel if it travels 5 feet down the road.

I know the circumference of the circle is 2pi. but how do i find out how many times does it rotate?

Question 6 states: If the , what is and what is ?

i know that and that and . So would everything be 1? 1=hypotenuse/adjacent/opposite?

I greatly appreciate everybodies help.

Thank You
