Find the radian measure corresponding to the following degree measure : 7°30′
Find the Radian Measure Corresponding to the Following Degree Measure : \( 7^\circ 30′ \) First convert minutes into degrees: \[ 30′ = \frac{30}{60}^\circ = \frac{1}{2}^\circ \] Therefore, \[ 7^\circ 30′ = 7.5^\circ = \frac{15}{2}^\circ \] To convert a degree measure into radians, we use the formula: \[ \text{Radian} = \text{Degree} \times \frac{\pi}{180^\circ} \] Conversion
