2.5 cubic metresImproved answer:Volume = pi*radius2*lengthVolume = pi*0.252*5 = 0.9817477042 cubic meters or about 1 cubic meter
Volume = pi*3.52*12 = 147*pi cubic meters
It is: pi*6*6*4 = 144*pi cubic meters
Volume of the cylinder = pi*0.652*3 = 3.982 cubic meters rounded to 3 dp
Volume of sphere: 4/3*pi*9^3 = 972*pi cubic meters
6 meters
1.5 meters is about 60 inches and so: pi*60squared*5 = 18000*pi cubic inches
Presumably these are the dimensions of a cylinder that has length of 28.26 meters and a circumference of 3.49 meters? First we have to find the radius by dividing 3.49 by 2*pi which works out as 0.5554507514 Volume of a cylinder = pi*radius2*length Volume = pi*0.55545075142*28.26 = 27.39133172 cubic meters
volume of a right circular cylinder is v = (pi)(h)(r^2) if you want the answer in cubic meters the height and the radius must be in meters.
Volume = pi*4.42*67.8 = 4123.67965 cubic meters
Use the formula: pi * r^2 * h where r is the radius, h is the height, * means multiply and ^2 means to the power of 2 or squared Vol = pi * 4^2 *7 = pi * 16 * 7 = pi * 112 = 351.9 cubic metres
Volume of a sphere = 4/3*pi*radius3 Volume = 4/3*pi*93 = 3053.628 cubic meters to 3 dp
