What is the first piece of the formula for a sphere?
4/3
List the first two pieces of the sphere volume formula
4/3 and Pi
List all the pieces of the sphere formula including what pi is equal to and multipication
4/3 x 3.14 x r to the power of three
How do you find the radius if not given on volume of a sphere problem?
Half the diameter
What is the circumference, diameter, radius?
Around the whole circle is circumference, a line that splits the sphere in half and goes to the South Pole of the sphere to the North Pole of the sphere is diameter, radius half of diameter and goes to the circumference to the diameter
What is the first step into finding pi
Diameter x Pi = Circumference
How do you get 3.14 (pi)
You do circumference divided by the diameter
Pi x diameter will give you the circumference
So then divide
Ok finally into sphere volume problems!
If the sphere radius is 3 inches then what is the volume for the sphere?
113.04 cubic inches
If the diameter is 16 inches then what is the volume of the sphere? (Round to the nearest thousandth when you got your answer)
2143.573 cubic inches
Solve the volume of a sphere problem
X = 9+10+5
X=diameter
Units is cubic inches

If 97 inches is the diameter of the sphere then what is the sphere’s volume?
Round to the nearest hundred thousandth
477632.20333 cubic inches
Solve this volume of a sphere problem
If 20 inches is the diameter, then what is the volume of the sphere?
Round to the nearest whole number
4187 cubic inches
X= Diameter
3X + 1 = 10
Solve, what is the volume for this sphere.
Units is cubic inches
14.13 cubic inches
Well ur doomed, however you’re lucky that you get two hints, if you manage to get this correct, you get a little Hershey bar. Ok here we go..
X=Circumference ROUND TO THE NEAREST 100 Million
2x - 32.2 = 128
Unit is cubic inches
7189.43813458 cubic inches
