triangles don't have volume or diameter, so I'm not sure what you're trying to ask.
Volume = 1/3*pi*202*12 = 5026.548 cubic feet (to 3 decimal places)
The area of triangle is : 12.0
Area = 1/2*12*14 = 84 square feet
24 ft2
113.1 square feet.
I got: 2,712.96 cubed.
Volume = 1/3*pi*202*12 = 5026.548 cubic feet (to 3 decimal places)
The area is 120ft2
The area is 78ft2
Volume = 2,111.15026 ft3
The area of triangle is : 12.0
Volume of a pyramid = 1/3*base area*height
Area = 1/2*12*14 = 84 square feet
24 ft2
113.1 square feet.
113.1 square feet.
Volume of cylinder = {pi} x radius2 x height Volume = {pi} x (18.5in/2)2 x 33in ~= 8870.5 cu in 1in = 1/12ft 1cu in = 1in x 1in x 1in = 1/12ft x 1/12ft x 1/12ft = 1/1728cu ft 8870.5 cu in = 8870.5 x 1/1728 cu ft ~= 5.13 cu ft
