Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
An arc is a part of total circumference of circle and length of that arc is the measurement of linear distance.
Since we know the formula for "Length of an arc " , we get
Hence, Option 'C' is correct.
If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be
then will also be a solution.
