v = pi r^2 h
That is the formula for the volume of a cylinder.
Therefore, the volume is
v = pi (4) ^ 2 * 12
v = 192pi
(That's the best form to leave the answer in, but if you want it as a number, multiply pi -about 3.14- by 192)
The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.
(12ft x 12ft) square =144 sq ft. 12ft x (12 ft square) is 1728 cu ft.
12ft*25ft = 300 square feet
14ft x 12ft = 168 sq ft = 15.6 m2
Assuming it's a box shape, the volume will be 11 x 12 x 9 = 1,188 ft3, or, in cubic metres, 33.64 m3.
Volume = 2,111.15026 ft3
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
r = 6 ft C = ~37.7 ft
Volume of a pyramid = 1/3*base area*height
"12 ft round" is not very clear; is 12 feet the radius, the diameter, or the circumference? After deciding that, convert all units to a common unit (convert all to feet, or all to inches), then use the formula for a cylinder, V = pi x radius2 x height.
Volume of a ball or sphere measured in cubic units = 4/3*pi*radius3

This cylinder will require 1.4 cubic yards of concrete (this assumes a length of 12' and a width of 2').
Valerie is installing a 20ft by 12ft swimming pool surrounded by a 6ft deck. What is the total area of the deck?
triangles don't have volume or diameter, so I'm not sure what you're trying to ask.
