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.
That's a total of 20 square yards.
12ft*25ft = 300 square feet
14ft x 12ft = 168 sq ft = 15.6 m2
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

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.
This cylinder will require 1.4 cubic yards of concrete (this assumes a length of 12' and a width of 2').
