Dear Math Blog Post, Week 6
My brain has gotten stuffed with more information. Every day, it’s something new. Do I always remember what I learned after the lesson? Not always but then they force me to use it the next day so I am forced to remember, and the information gets drilled into my head. This week, I remember learning how to find the volume and surface area of a hemisphere.
To find the volume of a hemisphere, you will use this formula:
For example, if you wanted to find the volume of a hemisphere with a radius of 2, this is what you would do:
When you do the surface area, it gets slightly more math-y. There are 2 exposed parts in the surface area of a hemisphere; the bottom half and the circle on top. When you calculate the surface area, the two must be added together.
The formula and an example question for finding the surface area of a hemisphere are in the picture below.
