#### Storyboard Text

• New lesson : Degrees to π﻿﻿ Radians π﻿﻿/180 and 180/π
• Good morning students today will be learning how to convert degrees to radians and radians to degrees ﻿
• In this case we refer back to the formula but we use this now to convert π﻿﻿ radians to degrees and the formula used is 180/π﻿
• convert the following to pi﻿: 225° ,﻿ 360°
• im so lost﻿
• ﻿We don't understand how to solve them can yous please explain how we use the formula
• Thank you boys for explaining ,Now Amanda can you answer the first question and Judy can you answer the second ﻿?
• Daniel and Ahmad can you guys solve this together solve these two ?﻿
• ﻿Yes and the first rule is to see what they want it in so since they want it in pi we use the formula π﻿﻿/180
• convert the following to pi﻿: 225° ,﻿ 360°
• That means that we will have 225° *π﻿﻿/180 ﻿= 5π﻿﻿/4 360°*π﻿﻿/180 ﻿=2π﻿
• convert the following to degrees﻿: π﻿/4 ,﻿ 3π﻿﻿/2
• With that being said we will multiply π﻿/4 * 180/π﻿ = 45° 3π﻿﻿/2 *180/π = 270 ° ﻿
• convert the following : 1)π﻿/4 ,﻿ 2)60°
• ﻿okay so since they want it in degrees we use the formula 180/π﻿ therefore its will be 1π﻿/2 *180 = 90°
• convert the following : 1)π﻿/4 ,﻿ 2)60°
• From what i understand we are going to use the formula π﻿﻿/180 so 60 * π﻿﻿/180 = π﻿﻿/3
