This week in math 10 we learned the surface area and volume of a sphere and hemisphere. At first it was tricky to get down and hard to remember the formula equations, but eventually I got it in simple steps at a time.

To find the volume of a sphere you need to:

Step 1: Find your formula

Step 2: Fill in the variables that you know

Step 3: Solve the exponent

Step 4: Multiply 4/3 by pi

Step 5: Multiply the two numbers you’re left with

Final Answer

Volume of a hemisphere

Step 1: Find the formula

Step 2: Divide the volume of the sphere by 2

Final Answer
