Question 1
What is the formula for calculating the exact offset?
- O = R + sqrt(R^2 + x^2)
- O = R - sqrt(R^2 - x^2)
- O = sqrt(R^2 + x^2)
💡 Hint: Recall the relationship between radius and offsets.
Question 2
True or False: An approximate calculation for large circles is always used.
- True
- False
💡 Hint: Consider when exact calculations might be more necessary.
