Q. If θ=23π radians, what is the value of θ in degrees?
Understanding radians and degrees: Understand the relationship between radians and degrees.One complete revolution around a circle is 360∘, which is also equal to 2π radians. Therefore, the conversion factor between radians and degrees is 180∘ per π radians.
Converting radians to degrees: Convert (3π)/2 radians to degrees.To convert radians to degrees, multiply the radian measure by the conversion factor (180/π).So, θ in degrees is (3π)/2×(180/π).
Performing the calculation: Perform the calculation.(23π)×(π180)=(23)×180=3×90=270
Verifying the result: Verify the result.Since (23π) radians is three-quarters of the way around a circle, and a full circle is 360 degrees, three-quarters of 360 degrees is indeed 270 degrees. This confirms that our calculation is correct.
