Question

Convert -630° from degrees to radians. use the value of π found on a calculator and round answers to four decimal places, as needed.

Answer 1

$\text{The formula to convert degrees to radians:}\\\\\dfrac{\alpha\pi}{180}$


$\text{We have}\ \alpha=-630^o\\\\\text{substitute}\\\\-630^o=\dfrac{-630\pi}{180}=-\dfrac{7\pi}{2}=-3.5\pi\approx-10.9956$

Answer 2

Formula: d * π/180°

d = degree of the angle

We are given -630° so this will be substituted for d.

Solve:

-630° * π/180° ≈ 10.99557 rad

Best of Luck!
