A circumference of 6.28 feet.
Circumference = 2*pi*radius or diameter*pi
Circumference of a circle = pi*diameter or 2*pi*radius Circumference = 11.62389282 inches
Circumference of a circle = 2*pi*radius or diameter*pi
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
Circumference of a circle = 2*pi*radius or diameter*pi so in this case circumference = 2 x 3.142 x 1.5 ft = 9.42 ft
Radius of a circle = circumference/2*pi
A circumference of 6.28 feet.
The circumference of a circle with a radius of 4 ft is: 25.13 feet (r x 2 x Pi = circumference).
Circumference = 2*pi*radius or diameter*pi
Circumference of a circle = pi*diameter or 2*pi*radius Circumference = 11.62389282 inches
Circumference of a circle = 2*pi*radius or diameter*pi
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
circumference (2piR) = 80, so R= 12.72.. Now Sq ft (area) = 2(pi)(R)(R) = 1018.18
12.566 feet.
Circumference = 2*pi*r = 169.6 feet.
circumference = 2 x π x radius ~= 31.4 ft
