Question:

Convert the angle in degrees to radians. Round to two decimal place.

{eq}\displaystyle 288^\circ \\ 288^\circ = \square \text{ radians } {/eq}

Conversion of Measuring Angle from Degree to Raidan:

The conversion of measurement of an angle from degree to radian is done by the product of the measurement in degree and the quotient of {eq}\pi {/eq} over {eq}180. {/eq} For example,

$$5^{\circ} = 5 \times \dfrac{\pi}{180} \Rightarrow 0.0873 \ \text{radian}$$

• Let us consider the given angle as {eq}\theta = 288^{\circ} {/eq}

To convert the angle from degrees to radians, we multiply the angle by {eq}\dfrac{\pi}{180} {/eq}, as follows:

\begin{align*} \theta &= 288^{\circ} \\[0.3cm] &= 288 \times 1^{\circ} \\[0.3cm] &= 288 \times \dfrac{\pi}{180} & \left[ \because 1^{\circ} = \dfrac{\pi}{180} \ \text{radian} \right] \\[0.3cm] &= \dfrac{288 \pi}{180} \\[0.3cm] &= \dfrac{288 \times 3.14159}{180} \\[0.3cm] &= \dfrac{904.77792}{180} \\[0.3cm] &= 5.02654 \\[0.3cm] \therefore \theta &\approx 5.03 \end{align*}

Hence, the angle of measure in radians is {eq}\color{blue}{5.03} {/eq}. Radians and Degrees: Definition & Examples
