The circumference is approximately 527.79 units.
The formula is: C = 2*Pi*r
For any circle . . .Diameter = circumference/pi .
A circumference of 263.89 cm
Circumference equals pi times diameter; so C = 84*pi or about 263.9.
84/3.14 =27 So the diameter of this circle is about 27 inches
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
With a radius of 84cm? about 528cm, or 5.28m. C=2(pi)r = 2(~3.14)(84) =~528
For any circle . . .Diameter = circumference/pi .
A circumference of 263.89 cm
circumference = 84*pi
Circumference equals pi times diameter; so C = 84*pi or about 263.9.

The volume of a cylinder is pi*(radius)^2*height. We are not given the radius here, but we know the circumference. Circumference is 2*pi*radius. So radius is equal to the circumference/(2*pi). We can then substitute this into the equation for volume to get: V=pi*(circumference/(2*pi))^2*height=(circumference)^2/(4*pi)*height._________________________________________________________________For your problem we have circumference=84 inches and height=32 inches. So:(84 inches)^2/(4*pi)*32 inches=7056 square inches/(4*pi)*32 inches=1764 square inches/pi*32 inches=56448 cubic inches/pi=17967.9564553 cubic inches which is about 17968 cubic inches.
This is missing some information. For instance, it does not say what 84 is. Is it the radius, the circumference? See the link below for a step by step guide to finding a diameter.
84/3.14 =27 So the diameter of this circle is about 27 inches
(14/84) x 360° = 60°
Diameter = 84 in Radius = 42 in = 3.5 feet Area of circle = pi x r x r = 3.1415 x 3.5 x 3.5 =38.483 square feet
Assuming you are asking for the surface area of a cylinder of height 84 in and circumference (of end) of 26 in: 12 in = 1 ft circumference = 2 x π x radius → radius = circumference ÷ (2 x π) surface_area = 2 x area_of_ends + curved_area = 2 x π x radius2 + height x circumference = 2 x π x (circumference ÷ (2 x π))2 + height x circumference = circumference2 ÷ (2 x π) + height x circumference = (26 ÷ 12 ft)2 ÷ (2 x π) + (84 ÷ 12 ft) x (26 ÷ 12 ft) ≈ 15.91 sq ft
