I have a pie chart showing a girl's daily activities. I have the angles and I need to calculate the time in hours. This girl spends 150 degrees of her time sleeping. How many hours is that (explanation included pls). Thanks

Well if 360 degrees is 24 hours, find how many hours one degree is. 24 hours -> 360 degrees means (24/360) hours -> degree. Then multiply that by 150: (150*24/360) -> 150 degrees.

How many hours is that (explanation included pls). Thanks $\displaystyle \frac{150}{360} \cdot 24$ hours. Do you see why?
So, if I worked it out well, the answer should approximately equal to 7 hrs.

Ok, I just rechecked the sum and the answer is 10 hrs. Hope it's correct
