Answer:

Diameter = [tex]\frac{T}{\pi}[/tex]  units

Step-by-step explanation:

There are 2 formulas that we have for circumference of a circle, shown below.

  1. [tex]C=2\pi r[/tex]
  2. [tex]C=\pi d[/tex]

This comes from the fact that twice radius (r) is equal to diameter (d).

Since the question asks for diameter given circumference, we will use #2 formula from above because it relates circumference and diameter.

C = T [given]

d = ???

Let's find by substituting in formula:

[tex]C=\pi d\\T = \pi d\\d=\frac{T}{\pi}[/tex]

Hence the diameter is  [tex]\frac{T}{\pi}[/tex]  units
