Answer:
C. 81π=4/3π^3
Step-by-step explanation:
The volume of a sphere will required the radius of a sphere to be multiplied by itself to the power of three seeing that this is the only metric amount in the volume equation. The volume of a sphere is defined as the following:
V=4/3*π*r^2
The volume is given as 81π
Therefore the expression can be written as:
81π=4/3π^3
Option C is the correct equation
