Answer:

d ≈ 135.1 m

Step-by-step explanation:

The circumference formula is:[tex]C=2\pi r[/tex]

In order to solve this, just substitute 43 cm into C, to get:

[tex]43 m=2\pi r[/tex]

Divide 43 by 2 times pi to find the radius:

[tex]r=67.54424205[/tex]

Then in order to find the diameter, double the number of the radius:

[tex]d=7.54424205[/tex]×[tex]2[/tex]

[tex]d=135.0884841 m[/tex]

d ≈ 135.1 m
