It is 4/3*pi*r3 = 33.5 cubic units approx.
The volume of a sphere with a radius of 2cm is about 33.5cm3
Volume of a sphere is 4/3 pi times the cube of its radius.
The volume of a sphere is given by the formula V =⁴⁄ ₃πr3The volume of a sphere with radius 7cm = ⁴⁄ ₃π73 = 1436.76 cm3 (to 2 dps)
Divide the diameter by 2 to get the radius. Then use the standard formula for the volume of a sphere.
Vol = 4/3*pi*r3 so given the volume, you can calculate the radius. Height of sphere = 2*radius.
cubic meters
Volume of the sphere: 4/3*pi*2^3 = 33.5 cubic meters to one decimal place
you need the mass and radius of the sphere- density = mass divided by volume, so mass/volume. the volume of a sphere is 4 divided by 3 multiplied by pi multiplied by the radius squared. 4/3(π)(r^2).
Let the radius of the sphere be r. surface area of the sphere = 4 * pi * r^2 volume = (4 * pi * r^3)/3
Volume of half a sphere = 2/3*pi*radius3 Volume = 2/38pi*103 = 2094.395102 cubic units
33.51 cm^3
If that's the radius, use the standard formula for the volume of a sphere.If that's the diameter, divide it by 2 to get the radius; then you can use the standard formula for the volume of a sphere.
