This formula is used to calculate the area of a circle using the diameter:

A= 1/4πd².

Rearrange the formula to calculate the diameter of a circle.
d = _____

Respuesta :

Step-by-step explanation:

[tex]a = \frac{1}{4} \times \pi \times {d}^{2} [/tex]

[tex]4a = \pi \times {d}^{2} [/tex]

[tex] \frac{4a}{\pi} = {d}^{2} [/tex]

[tex] \sqrt{ \frac{4a}{\pi} } = d[/tex]

Answer:

d= 2√a/π

     

To calculate the diameter, rewrite the formula to isolate D

Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution

Simplify further to get the solution
