Volume of any 3-dimensional object is always 'Cubic'. 'Squared' refers to area. The volume of a cylinder is V = pir^2h Where pi r^2 refers to the area of the circular profile of the cylinder., which is a 'squared' value/ 'h' is the height of the cylinder , which is a linear value. When a squared value is multiplied to a linear value , it becomes a cubic value.
The volume of a cylinder equals the area of the base times the height, which equals pi x radius squared x height. Inserting the numbers, V = pi x (2 m.) squared x 5 m. = pi x 4 m. squared x 5 m. = 20 x pi meters cubed or 20 x pi cubic meters.
a cubed
Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)
No, 2 cubed is not the same as 3 squared. 23 = 8 32 = 9
n squared x n = n cubed but that does not equal 21. ---------------------------------------------------------------- Here is the correct version: We are looking for Pi squared times Pi which is Pi cubed Now Pi can never be written out exactly because its decimal number goes on for ever. However we can take a good approximation to Pi as 3.142 So Pi cubed = 3.142 x 3.142 x 3.142 = 31.018339 = 31.02 to 4 places.
The original value of Pi is 3.1415965. Pi squared is 9.86960440109. Pi times 2 is 6.28318530718. Pi cubed is 31.0062766803.
Cone: 1/3 ( pi r squared h). sphere: 4/3 pi r cubed
Pi has many usages in mathematics some of which are:- Area of a circle = pi*radius squared Circumference of a circle = diameter*pi or 2*pi*radius Surface area of a sphere = 4*pi*radius squared Volume of a sphere = 4/3*pi*radius cubed Volume of a cone = 1/3*pi*radius squared*height The value of pi is found by dividing the circumference of a circle by its diameter
2 squared --> 4 2 cubed --> 8 3 squared --> 9 3 cubed --> 27
Area: 4*pi*6 squared = 144*pi square units Volume: 4/3*pi*6 cubed = 288*pi cubic units
if it is a can, the formula is pi*r^2*length 1.75/2 is 0.875 radius. squared is 0.765625 units squared. x 3.5 x pi is: 8.42 units cubed
It is cubed.
The volume is cubed and the surface area is squared.
I'm pretty sure that perimeter is squared and volume is cubed.

shall assume the 18ft measurement is the diameter, not radius. 18ft = 5.486m = diameter 52in = 1.321m = depth pi x radius(squared) = area of the circle pi x 2.243(squared) = 15.8055 meters squared area x depth = volume in meters cubed 15.8055 x 1.321 = 20.879 meters cubed 1 meter cubed = 1000L 20.879 meters cubed = 20879L 20879L is: 5515.648 US Gallons 4592.738 UK Gallons
