How many radians is 20 degrees?

To convert degrees to radians, you can use the formula:

radians = degrees × (π / 180)

In this case, we want to convert 20 degrees to radians. So, we substitute 20 for degrees in the formula:

radians = 20 × (π / 180)

This simplifies to:

radians = (20π) / 180

Now, we can reduce the fraction:

radians = (1π) / 9

Therefore, 20 degrees is equal to:

20 degrees = π / 9 radians

In summary, 20 degrees is approximately 0.3491 radians when expressed as a decimal.
