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.
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.
you measuresit by the radius
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.
It's the extension of the sphere's radius drawn to that point.
