4. :The question is based on a faulty premise; the surface area of a sphere has been calculated many times in many ways.
5. In " On the Sphere and Cylinder, " he gives upper and lower bounds for the surface area of a sphere by cutting the sphere into sections of equal width.
6. It's difficult to find surface area of a sphere in a sentence. 用surface area of a sphere造句挺難的
7. Since the surface area of a sphere = 4? r?where r is the radius, every doubling of the radius results in a four-fold increase in the sphere's surface area.
8. For homogeneous nucleation the nucleus is approximated by a sphere and so has a free energy equal to the surface area of a sphere, 4?r 2, times the surface tension & sigma;.
9. The use of ? 0 instead of k 0 in expressing Coulomb's Law is related to the fact that the force is inversely proportional to the surface area of a sphere with radius equal to the separation between the two charges.
10. This formula contains a, but it is unclear if that is fundamental in a physical sense, or if it just reflects the in the expression { 4 \ pi r ^ 2 } for the surface area of a sphere with radius r.
11. Because the surface area of a sphere is four times the cross-sectional surface area of a sphere ( i . e . the area of a circle ), the average TOA flux is one quarter of the solar constant and so is approximately 340 W / m?
12. Because the surface area of a sphere is four times the cross-sectional surface area of a sphere ( i . e . the area of a circle ), the average TOA flux is one quarter of the solar constant and so is approximately 340 W / m?
13. So, years ago I noticed that the volume of a sphere is \ frac { 4 } { 3 } \ pi r ^ 3 and the derivative of this, with respect to r, is 4 \ pi r ^ 2, which is the surface area of a sphere.
14. where S _ n is the surface area of a unit ball in the space ( that is, S _ 2 = 2 \ pi, the circumference of a circle with radius 1, and S _ 3 = 4 \ pi, the surface area of a sphere with radius 1 ).
15. Combining the formulas for the Schwarzschild radius of the black hole, the Stefan Boltzmann law of blackbody radiation, the above formula for the temperature of the radiation, and the formula for the surface area of a sphere ( the black hole's event horizon ), several equations can be derived:
16. This holds for areas in three dimensions as well as in the plane : for instance, the surface area of a sphere is proportional to the square of its radius, a fact that is manifested physically by the inverse-square law describing how the strength of physical forces such as gravity varies according to distance.
