dont take my word for it but,
The volume of a cylinder can be calculated using the formula:
V = x * r^2 * h
Where:
V is the volume of the cylinder
x is the value of pi (3.14 in this case)
r is the radius of the cylinder (half the diameter, so 2 feet in this case)
h is the height of the cylinder
Plugging in the values from the problem, we get:
V = 3.14 * 2^2 * 6
= 3.14 * 4 * 6
= 75.36 cubic feet
So the volume of the rainwater collection tank is 75.36 cubic feet. The answer is therefore 75.36 cubic feet (Option B).
