Convert from Radians to Degrees -(9pi)/4

Problem

−(9*π)/4

Solution

1. Identify the conversion factor between radians and degrees, which is 180/π

2. Multiply the given radian measure by the conversion factor to cancel out the π units.

−(9*π)/4⋅180/π

3. Simplify the expression by canceling π from the numerator and denominator.

−(9⋅180)/4

4. Divide 180 by 4 to make the multiplication easier.

180÷4=45

5. Calculate the final product of −9 and 45

−9⋅45=−405

Final Answer

−(9*π)/4=−405
