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
