C If we let a be the smallest sector angle and r be the difference between consecutive sector angles, then we have the angles a, a+r, a+2r, ⋯. a+11r. Use the formula for the sum of an arithmetic sequence and set it equal to 360, the number of degrees in a circle....
Central Angle Formula Lesson Summary Frequently Asked Questions What is a central angle? A central angle is an angle whose vertex is present at the center of a circle formed by the two radii as the sides of the angle. How do you find the central angle of a circle? The measure of a ...
A circle is cut into several equal sectors. If the central angle of each sector is 60 degrees, then the number of sectors is ___. A. 3 B. 4 C. 5 D. 6 相关知识点: 试题来源: 解析 D。本题考查圆形的分割计算。因为圆的圆心角是 360 度,每个扇形的圆心角是 60 度,所以 360÷60=6...
The N data sets are assigned to a 360/N degree sector, and each point within a data set is plotted inside the appropriate sector. This is done by computing the point's polar coordinate, and mapping the resulting angle component on to the appropriate 360/N degree sector, while retaining ...
But overall the search for silver bullets anywhere in energy/climate is likely oversimplifying whereas recognizing the tapestry of options and solutions will do the most good long-term. Curious to see where this angle goes, though-- thanks for sharing John! SEE ALL 2 COMMENTS ...
