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.
Answer:
Q and T
Step-by-step explanation:
these seem to be the most likely choice
Distance = √(x2 − x1)^2 + (y2 − y1)^2
Substitute in the coordinates.
Distance = √(3 − (-7))^2 + ((-4) − 5)^2
Simplify by using order of operations/PEMDAS.
Distance = √(10)^2 + (-9)^2
Distance = √100 + 81
Distance = √181
The distance is √181 or 13.45362. However, I suggest leaving the distance as √181.
