Express 40% of a right angle into radian measure

1 answer

A right angle is equal to 90 degrees, so 40% of a right angle is:

40% of 90 degrees = 0.4 x 90 = 36 degrees

To convert degrees to radians, we use the formula:

radians = degrees x π/180

where π (pi) is approximately equal to 3.14.

Plugging in the value of 36 degrees, we get:

radians = 36 x π/180
radians = 0.6283 radians (rounded to four decimal places)

Therefore, 40% of a right angle is approximately equal to 0.6283 radians.
