Formula for volume of a sphere = 4/3*pi*radius3 measured in cubic units.
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
use the formula 4/3*π*radius3 to find the volume of a sphere.
The formula for the volume of a sphere is based on the radius of the sphere. It is equal to 4/3 multiplied by pi, multiplied by the radius cubed.
(pi)R2 is the formula for the area of a circle. It won't help you find the volumeof a half sphere, at least not without some calculus.What you need is the formula for the volume of a sphere: V = 4/3 pi R3 .Do I have to explain that the volume of a half sphere is just half of that ?
Surface area of a sphere = 4 x (pi) x (radius)2
The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2.

The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
how do you find the mass of a sphere Volume x density => 4/3(pi)(r)3 x density
Depends on the information that you DO have. Half the diameter is the easiest formula, but that only works if you know the diameter.
Four thirds of pi x the cube of the radius
