The radius of the base is half of the diameter, so it is 8ft / 2 = <<8/2=4>>4ft.
The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.
Plugging in the given values, V = π(4ft)²(20ft).
Simplifying further, V = π(16ft²)(20ft).
The volume is then V = 320π ft³.
To find the volume to the nearest tenths place, we must approximate the value of π as 3.14.
Therefore, the volume is approximately V ≈ 320 * 3.14 ft³ ≈ 1004.8 ft³. Answer: \boxed{1004.8}.
A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubic ft, to the nearest tenths place?

that isnt right bot :(
Apologies for the mistake. Let's solve it correctly.
The radius of the base is half of the diameter, so it is 8ft / 2 = 4ft.
The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.
Plugging in the given values, V = π(4ft)²(20ft).
Simplifying further, V = π(16ft²)(20ft).
The volume is then V = 320π ft³.
Approximating the value of π as 3.14, the approximate volume is:
V ≈ 320 * 3.14 ft³ ≈ 1004.8 ft³.
Therefore, the volume of the cylinder is approximately 1004.8 cubic feet, to the nearest tenth place.
