We need to convert one radian to degrees. These are units of angle measurement. Use the relation \[{\pi ^c}\] \[ = \] \[{180^ \circ }\].Complete step by step solution:One radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle. That means, the magnitude in radians of such a subtended angle is equal to the ratio of the arc length to the radius of the circle;that is: \[\theta = \dfrac{r}{s}\] Where \[\theta \] is the subtended angle in radians, \[s\] is arc length, and \[r\] is radius.A degree is a measurement of a plane angle in which one full rotation is 360 degrees.From the relation :\[{\pi ^c}\] \[ = \] \[{180^ \circ }\]\[ \Rightarrow \] \[{1^c}\] \[ = \] \[{\left( {\dfrac{{180}}{\pi }} \right)^ \circ }\]Substitute the value of \[\pi \] in the above equation:\[ \Rightarrow \] \[{1^c}\] \[ = \] \[{\left( {\dfrac{{180}}{{\left( {\dfrac{{22}}{7}} \right)}}} \right)^ \circ }\]\[ \Rightarrow \] \[{1^c}\] \[ = \] \[{\left( {\dfrac{{180 \times 7}}{{22}}} \right)^ \circ }\]\[ \Rightarrow \] \[{1^c}\] \[ \approx \] \[57.2958\]The above value is often approximated as :\[{1^c}\] \[ = \] \[{57^ \circ }\].Note:Both radian and degree are the units for measuring plane angle. A degree is symbolized by the ‘\[^ \circ \]’ symbol, while radian is symbolized by ‘\[^c\]’ symbol (both written in superscript). Radian is the S.I. unit for a plane angle.Recently Updated PagesQuestions & Answers - Ask your doubtsA man running at a speed 5 ms is viewed in the side class 12 physics CBSEState and explain Hardy Weinbergs Principle class 12 biology CBSEWhich of the following statements is wrong a Amnion class 12 biology CBSETwo Planoconcave lenses 1 and 2 of glass of refractive class 12 physics CBSEThe compound 2 methyl 2 butene on reaction with NaIO4 class 12 chemistry CBSEQuestions & Answers - Ask your doubtsA man running at a speed 5 ms is viewed in the side class 12 physics CBSEState and explain Hardy Weinbergs Principle class 12 biology CBSEWhich of the following statements is wrong a Amnion class 12 biology CBSETwo Planoconcave lenses 1 and 2 of glass of refractive class 12 physics CBSEThe compound 2 methyl 2 butene on reaction with NaIO4 class 12 chemistry CBSE
