Q. Convert the angle −4.5 radians to degrees, rounding to the nearest 10th.Answer:
Understand radians and degrees: Understand the relationship between radians and degrees. One radian is equal to 180/π degrees. To convert radians to degrees, we multiply the radian measure by 180/π.
Convert −4.5 radians: Convert −4.5 radians to degrees.To convert −4.5 radians to degrees, we multiply −4.5 by π180.Calculation: (−4.5 radians) * (π180) degrees/radian) = −4.5×180/π degrees
Perform calculation: Perform the calculation.Using a calculator, we find that −4.5×180/π is approximately −257.5959 degrees.
Round to nearest 10th: Round the result to the nearest 10th. Rounding −257.5959 to the nearest 10th gives us −257.6 degrees.
