Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared to the same volume of the material. For example, let us consider a sphere of radius r: The surface area of the sphere will be 4πr2 The volume of the sphere = 4/3(πr3) Therefore the surface area to the volume ratio will be 4πr2/{4/3(πr3)} = 3/r It means that the surface area to volume ration increases with the decrease in radius of the sphere and vice versa.
The surface area of a sphere with a radius of 2 is about 50.27 units2
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
The surface area of a sphere with a radius of 7 is about 615.8 units2
The sphere's surface area is ~1,017.9 square units.
If they have the same radius then it is: 3 to 2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
The surface area of a sphere with a radius of 5m is 314.2m2
The surface area of a sphere with radius 6 is: 452 square units.

The surface area of a sphere that has a radius of 10 is: 1,260 square units.
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.
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
The surface area of a sphere with a radius of 2 is about 50.27 units2
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
