which expression converts 45° to radians?\n45°·180°\n45°·\\frac{180°}{\\pi}\n45°·\\frac{\\pi}{180°}\n45°·\\pi

Answer:

C. $45^{\circ}\cdot\frac{\pi}{180^{\circ}}$

Explanation:

Step1: Recall conversion formula

To convert degrees to radians, we use the formula: radians = degrees $\times\frac{\pi}{180^{\circ}}$.

Step2: Substitute given degree value

Given the degree value is $45^{\circ}$, substituting it into the formula gives $45^{\circ}\cdot\frac{\pi}{180^{\circ}}$.
