Depends on the information that you DO have. Half the diameter is the easiest formula, but that only works if you know the diameter.

How to get the formula to find radius in spherometer?
Treat the 3D sphere as a 2D circle. The radius for the sphere is the same radius as for the circle. No matter where on the sphere you place a mark, the distance (radius) from the mark to the centre of the sphere will always be the same as the circle.
Formula to find out the Earth's surface area?
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.

What is the formula to find the suface area of a sphere?
Surface area of a sphere = 4 x (pi) x (radius)2
Formula to find volume of the sphere?
Four thirds of pi x the cube of the radius
What is the formula for the volume of a sphere with radius that equals 5?
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
How do you find to the formula of a sphere?
you measuresit by the radius
How do you find the surface area of a sphere when its volume is 523.5987756 cubic cm?
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.
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.

Four thirds of pi x the cube of the radius
How do you find the volume of a sphere when the radius is 10?
Use this formula when the radius is known: V = 4/3(PI*r3)
What is the volume of a sphere with a radius of 10.2?
The formula to find the volume of a sphere us V = 4/3πr3, where V is volume, π is pi, which can be rounded to 3.14, and r is the radius. In order to find the volume of your sphere, the radius has to have a length unit, such as 10.2 cm or 10.2 inches.
What is the formula for the volume of a sphere with radius that equals 5?
The formula for the volume of any sphere isVolume = ( 4/3 pi ) x (cube of the radius)
What are the volume and radius and diameter of Mars?
Mars is almost a sphere and the volume of a sphere is: 4/3*pi*radius3 So find its radius and its volume can be found using the above formula
