Explanation
In geometry, a sphere is defined as a set of points that are all the same distance (r) from a given point in a three-dimensional space. The formula for calculating the volume of a sphere is:
Where r represents radius, and the Greek letter π ("pi") represents the ratio of the circumference of a circle to its diameter. In Excel, π is represented in a formula with the PI function, which returns the number 3.14159265358979, accurate to 15 digits:
=PI() // returns 3.14159265358979
To cube a number in Excel, you can use the exponentiation operator (^):
=A1^3
Or, you can use the POWER function:
=POWER(A1,3)
Rewriting the formula using Excel's math operators we get:
=4/3*PI()*B5^3
Or, with the POWER function:
=4/3*PI()*POWER(B5,3)
The result is the same for both formulas. Following Excel's order of operations, exponentiation will occur before multiplication.

PI Function
The Excel PI function returns the value of the geometric constant π (pi). The value represents a half-rotation in the radian angle system. The constant appears in many formulas relating the circle, such as the area of a circle....
POWER Function
The Excel POWER function returns a number raised to a given power. The POWER function is an alternative to the exponent operator (^).
