Fist you've got to find the volume of the sphere, if the radius was 4cm then it would be...4/3*pi*r3=268cm V of cylinder= pi*r2*l (the radius for example is 8cm) 268=pi*64*l L=268/64pi =1.3cm
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
The Volume of cylinder with radius of 4cm and height of 10cm is: 502.65 cm3
The circumference of a circle with a radius of 4cm is: 25.13 cm (r x 2 x pi)
radius is half the diameter. so 4cm.
The volume of a sphere with a radius of 4cm is about 268cm3
V = 268.08 cm3
The mass of a sphere is 4/3*pi*r3*d where r is the radius of the sphere and d is the density of the material of the sphere.
radius=4cm diameter=8cm *radius is half the diameter
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).

mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
Vol(3)/Vol(2.5) = 33/2.53 = 1.23 So Mass(3) = 1.23*Mass(2.5) = 1.23*500 = 864 grams
A cylinder with a radius of 4cm and a height of 2cm has a volume of 100.53cm3
The Volume of cylinder with radius of 4cm and height of 10cm is: 502.65 cm3
4cm
