Where:
d: Is the diameter of the circumference
According to the data we have to:
Substituting:
Rounding out we have that the diameter is: 80

9514 1404 393
Answer:
6 feet
Step-by-step explanation:
The volume of a cylinder is given by ...
V = πr^2·h
For a sphere, the volume is ...
V = 4/3πr^3
You want the volumes to be the same when h=8, so we have ...
πr^2·8 = 4/3πr^3
Dividing by πr^2, we have ...
8 = 4/3r
r = 3/4·8 = 6
The radius is 6 feet.
The possible digits could be 0, 1, 2, 3, or 4 as they would cause the entire number to round down instead of up.
