how do you find the mass of a sphere
Volume x density => 4/3(pi)(r)3 x density
Surface area of a sphere = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2
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)
The diameter of the sphere is 19.6 cm.
Use your volume formula and your radius to find volume. Next use the equation d=m/v or m=dv to find your mass of copper. Use your mass, atomic weight of copper, and avagadro's number to figure out your atoms.
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.
The formula for calculating the moment of inertia of a solid sphere is (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
The formula for calculating the moment of inertia of a hollow sphere is I (2/3) m r2, where I is the moment of inertia, m is the mass of the sphere, and r is the radius of the sphere.
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).
The moment of inertia of a solid sphere is given by the formula (2/5) m r2, where m is the mass of the sphere and r is the radius of the sphere.
To find the mass of a sphere, you need to know its density in addition to its volume. The volume ( V ) of a sphere can be calculated using the formula ( V = \frac{4}{3} \pi r^3 ). For a sphere with a radius of 4 cm, the volume would be approximately 268.08 cm³. If you provide the density of the material the sphere is made of, the mass can be calculated using the formula ( \text{mass} = \text{density} \times \text{volume} ).
The moment of inertia of a solid sphere is derived by integrating the mass of the sphere over its volume, taking into account the distance of each mass element from the axis of rotation. This integration results in the formula for the moment of inertia of a solid sphere, which is (2/5) mass radius2.
Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.
The center of mass of a sphere is its geometric center.
Formula for calculating the area of sphere is : 4 * pi * r * r
To find the mass of the gold sphere that displaces 2.3 mL of water, we can use the density of gold, which is approximately 19.32 g/cm³. Since 1 mL is equivalent to 1 cm³, the mass can be calculated using the formula: mass = density × volume. Therefore, the mass of the gold sphere is 19.32 g/cm³ × 2.3 cm³ = 44.49 grams.
The moment of inertia of a solid sphere about its diameter is (2/5)MR^2, where M is the mass of the sphere and R is the radius. This can be derived from the formula for the moment of inertia of a solid sphere about its center, which is (2/5)MR^2, by applying the parallel axis theorem.
