V = 4/3 πr3
A = Area
V = volume
d = diameter
r = radius
A sphere is a three-dimensional geometric shape where all points on the surface are equidistant from a fixed point called the center.
The properties of a sphere include:
The radius of the sphere is, for example, 8 cm. Thus, r = 8.
area of the sphere:
We use the formula
A = 4πr²
thus
A = 4 * 3.14 * 8 * 8
A = 803.84 cm²
volume of the sphere:
We use the formula
V = 4/3πr³
thus
V = 4/3 * 3.14 * 8 * 8 * 8
V = 2144.66 cm³
