Surface Area of Sphere Formula
To calculate the surface area of a sphere, multiply four by the circle constant (pi) by the radius squared. For example, the surface area of a sphere with a radius of is given by:
The surface area of the sphere with a radius of is approximately equal to units squared.
The area of a circle is given by the geometric constant π (pi) multiplied by the radius of the circle squared (A = πr²).
The volume of a sphere is given by four-thirds multiplied by π (pi) multiplied by the radius cubed.
