You have to cut the sphere in half and then measure across.
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.
A sphere with a volume of 50 units3 has a radius of 2.29 units. A sphere with twice the radius (4.58 units) has a volume of 402 units3.
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.
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.
Use this formula when the radius is known: V = 4/3(PI*r3)
The radius of a sphere is 1/2 of its height.

The radius of the sphere is ~16.395 units.
If the radius is 7 and the volume is 1232 the shape cannot be a sphere so you cannot find the height of a sphere when the shape is not a sphere!
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.
you measuresit by the radius
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.
A sphere with a volume of 50 units3 has a radius of 2.29 units. A sphere with twice the radius (4.58 units) has a volume of 402 units3.
The "area of a sphere" does not make sense. You must mean the "volume of a sphere". double radius = ...; double volume = 4. / 3. * 3.141592653589793 * radius * radius * radius;
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
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.
The radius of a sphere joins the center of the sphere to its circumference.
