The formula for calculating the charge density of a sphere is Q / V, where is the charge density, Q is the total charge of the sphere, and V is the volume 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.
The formula for calculating the surface charge density of a sphere is: Q / 4r, where represents the surface charge density, Q is the total charge on the sphere, and r is the radius of the sphere.
The formula for calculating the electric field of a sphere is E k Q / r2, where E is the electric field, k is the Coulomb's constant (8.99 x 109 N m2/C2), Q is the charge of the sphere, and r is the distance from the center of the sphere.
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
Cylinders and spheres are different geometric shapes with different properties. The formulas for calculating their volume and surface area reflect these differences in shape and dimensions. The formula for a cylinder involves multiplying the base area by the height, while the formula for a sphere involves powers of the radius to account for its spherical shape.
SA = 4 π r2 (SA is surface area = 4 (X) pi(3.142) (X) R(adius) squared
Surface area of a sphere = 4πr2
The formula for the surface area of a sphere is: 4 pi r 2
Surface area of a sphere = 4*pi*radius2
(4/3)*pi*r^3 pi is constant 3.14, r is radius of the sphere.
The formula for the surface area of a sphere is 4*pi*r2
The area of a sphere is 4 (pi) (radius)2. The area of 1/2 of the sphere is 2 (pi) (radius)2. If you want to add in the flat end of the hemisphere, that makes the total surface area 3 (pi) (radius)2.
V=4/3*Pi*r3 where r is the radius.
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
Surface area of a sphere = 4*pi*radius2
