This week I learned how to find a surface area and volume of a bunch of new shapes. But, the most interesting to me was the surface area and volume of a sphere. the formula is different than any other shapes. The cool thing is that the diameter is equal to the diameter or the radius x2, because it is the same all the way around. If you roll it than it says the same. Another thing to add onto this is that the shape of a hemisphere is equal to half of a sphere, the word hemi meaning half. But when finding the surface area of a hemisphere you cannot just divide it by two, you actually have to add the area of the base to the final answer.
