Convert each radian measure to degrees. See Examples 2(a) and 2(b). 11π/30

Verified step by step guidance

1. Recall the conversion formula from radians to degrees: \(\text{degrees} = \text{radians} \times \frac{180}{\pi}\).
2. Identify the given radian measure: \(\frac{11\pi}{30}\).
3. Substitute the radian value into the conversion formula: \(\frac{11\pi}{30} \times \frac{180}{\pi}\).
4. Simplify the expression by canceling out \(\pi\) in numerator and denominator: \(\frac{11}{30} \times 180\).
5. Multiply the remaining numbers to find the degree measure: \(11 \times \frac{180}{30}\).

Key Concepts

Radian Measure

A radian is a unit of angular measure based on the radius of a circle. One radian is the angle created when the arc length equals the radius. It is a standard unit in trigonometry and is related to degrees by the conversion factor 180°/π.

Degree Measure

Degrees are a common unit for measuring angles, where a full circle is divided into 360 equal parts. Degrees are often used in practical applications and can be converted to and from radians using the relationship 180° = π radians.

Conversion Between Radians and Degrees

To convert radians to degrees, multiply the radian value by 180/π. This conversion uses the equivalence of π radians to 180 degrees, allowing you to express angles in the more familiar degree measure.
