A question I had problems with in week 5 is 4. on page 171.
When finding the surface area of the circle I tried to find it with just the diameter but then I realized that you can only find the area of the circle with the radius so then I divided the diameter by 2 and then I went radius squared and multiplied that by pi.
Overall the 2 things I need to differentiate are the area of a circle and the circumference of a circle. I think what helped me is knowing what a diameter and a radius are.
New Formulas:
area of a circle- radius squared times pi.
