Problem

21

Solution

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

2. Multiply the given angle in degrees by this conversion factor to cancel out the degree units.

21⋅π/180

3. Simplify the resulting fraction by finding the greatest common divisor of 21 and 180 which is 3

(21*π)/180=(7*π)/60

Final Answer

21=(7*π)/60
