The diameter d of a sphere is twice the radius r. the volume of the sphere as a function of its radius is given by v(r)= 4/3(3.4)(r)^3

a) write the diameter d of the sphere as a function of the radius

The diameter d of the sphere as a function of the radius is given by

Step-by-step explanation:

Given:

The volume of the sphere as a function of its radius is given by

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

i dont know

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
