A kickball is a sphere, so to solve this, we are going to use the formula for the volume of a sphere:
where
is the volume of the sphere.
is the diameter of the sphere.
We know form our problem that the diameter of the kickball is 10 inches; since the kickball is a sphere,
. Lets replace that value in our formula to find
:
We can conclude that the volume of the kickball is
523.6 cubic inches.
You're just dividing in this problem
which if you divide both bottom and to portion by 3 it leads to
4/3
Initially started 20 feet from the ground .
Went uphill 83 feet.
So: 20 + 83 = 103. The coaster is 103 ft above at this point.
Went down 42 feet
So: 103 - 42 = 61.
Went up 128 feet
So: 61 + 128 = 189
Finally, went down 90 feet
So: 189 - 90 = 99
99 ft above ground.
