Nice video that has very clean instructions that are straightforward. Your popups were a nice touch. I found the layout was also helpful. The problem on the left and the work on the right worked because the problem was always visible. As a teacher I would have preferred the videos broken up by objective for 2 reasons. The first is I could use each objective together or separately and second the buffering took awhile on my computer because of the length.
The video is a nice introduction to the topic in a simplified form. I would use this video.

In this video, I really like how clear Ms. Enwia is in all of her steps. I like her explanation of sectors a lot. I also like that she went through examples with us, and that the examples were helpful for us to see how different the problems can seem. Overall, I think this video is quite helpful.

Ms. Enwia explains each step she takes and her work is very organized and easy to follow. I like that she gives an example with the area given and works backward to find the radius. And I like that to find the radius, we need to use another math skill of simplifying a radical. She did a great job explaining a sector of a circle and showing how to find the area of a sector. Perhaps the sector of the circle could be a separate video. Overall, nice video.
