 Hello and welcome to the session. In this session we will discuss a question which says that study the given circle graph carefully, showing the distribution of time spent by Samantha on Sunday. And answer the following questions. First is, on which activity does she spend her maximum time? Second is, how much time does she spend watching TV and studying? Third is, what is the degree measure for sector representing exercise? Fourth is, what percentage of time does she spend studying? And fifth is, what percentage of time does she spend playing tennis and with family? Now let us start with the solution of the given question. In this question we are given a circle graph showing the number of hours spent by Samantha on various activities on a Sunday. Now here you can see that this circle graph is divided into 1, 2, 3, 4, 5, 6 and 7 sectors. Each sector is representing a category or a part of set of data. And on this circle graph we can see that 8 hours are spent on sleeping, 1 hour is spent on exercise, 4 hours are spent on studying, 5 hours are spent with family and 2 hours spent on watching TV, playing tennis and eating. Here total number of hours is equal to 8 plus 1 plus 4 plus 2 plus 5 plus 2 plus 2. That is equal to 24. In the first part we have, on which maximum time is spent by Samantha. On this circle graph we see that the largest sector is this blue sector and it belongs to category sleeping. So the maximum time that she spent when studying. Now from this circle graph we see that number of hours spent watching TV is equal to and studying is equal to this number of hours spent studying that is 4 hours spent that watch is the degree measure for sector representing x is equal to 24. And from the pie chart that is from the circle graph we can see that she spent 24 hours on exercise. Also I am going to measure first circle is equal to 360 degrees that is 24 hours this is equal to 15 is equal to 15 degrees Now from this circle graph we see that studying which is equal to number of hours spent studying that is 4 upon total number of hours that is 24 into 100% This is equal to 16.6% which is approximately equal to 17%. So 17% of time is spent studying of time that she spent playing tennis. We see that number of hours family is equal to hours that is equal to 7 hours and with family. Therefore the required percentage is equal to 7 upon 24 into 100% That is equal to 29.1% which is approximately equal to 29% of her time is spent playing tennis and with family. Pollution of the given question that's all for this session hope you all have enjoyed the session.
