Answer:
The diameter d of the sphere as a function of the radius is given by
[tex]d(r) = 2\times r[/tex]
Step-by-step explanation:
Given:
The volume of the sphere as a function of its radius is given by
[tex]v(r)= \frac{4}{3}\times (3.14)(r)^{3}[/tex]
Function:
A function is like a machine that gives an output for a given input.
A function has an independent variable which is called the input of the function.
The output for a given input is called the dependent variable.
Here. 'r' is the radius of a sphere independent variable
d(r) is the function dependent variable i.e Diameter as a function of radius as an output.
∴ d ( r ) = 2 r
