does anyone have a youtube guide or somewhere where i can learn area and volume? I tried james lu guide but the area and volume part got way too confusing. If anyone has a video that they would recommend please could you share it :)
If you imagine pi r squared as a circle, to make it into a cylinder you can just multiply it by h (height) to essentially stretch that circle.
If you are doing geometry with algebra, then its always useful to make a rough sketch on a piece of paper as you do the question, its the first thing I do on any geometry question actually.
For area learn about squares, rectangles, triangles, and circles. For volume rectangular prisms, spheres, cones and pyramids.
The best way for area and volume is to visualize.
