　　Read the following sat test question and thenclick on a button to select your answer.

　　If θ=330°, what is the value of θ in radians?

　　A.3/2π

　　B.5/3π

　　C.7/4π

　　D.11/6π

　　澳际温馨提示：各sat数学考生在看过上述sat考试题目之后，自己分析解答，再看相应的sat考试答案及解析，会更有效哦!

　　答案：D

　　解析：

　　Recall that there are 2π radians in one revolution ofa circle. There are also 360° in one revolution of acircle.

　　This leads us to the following conversion: 2π radians=360°

　　If we divide both sides by 360, we have 1°=π/180 radians.

　　We can use this factor to convert degrees to radians.

　　The conversion is performed below.

　　330°=330*1°=330*π/180=11π/6

　　Alternatively, if we divide both sides of the equation 2π radians=360° by 12, we can concludethat π/6 radians=30°.

　　Since 330° is 11*30°, its measure in radians must be 11*π/6.

　　Either way, we have the following: 330°=11π/6.

　　如何，这道sat考试题目，sat数学备考生们可答对了?好啦，今天的sat考试资讯，到这里就全部告一段落了，若各位盆友还想掌握更多知识的话，欢迎继续锁定澳际教育sat培训频道，澳际将陆续更新!
