I need step by step instructions for finding answers to these questions and similar. I am confused on what formula
to use and then some of the formulas have extra steps.
- A 3-ft wide circular track for a camera dolly is set up for a movie scene. The two rails of the track form concentric circles. The radius of the inner circle is 62 ft. How much further does the wheel on the outer rail travel than the wheel on the inner track?
The correct answer is 18.8ft, but I got a different answer using the formula Area of a circle = (pie)(radius)^2. WHat should I be doing?
I am more interested in the formula’s used to solve these than the answers. Thank you SO much!
