Question

Cuanto mide el radio de un círculo si su área es de 2,122.64 cm2

PI= 3.14

Answer 1

Respuesta:

Explicación paso a paso:

[tex]Radio: r = ?[/tex]

[tex]Area: A = 2,122.64cm^{2}[/tex]

[tex]\pi =3.14[/tex]

Fórmula:

[tex]A=\pi *r^{2}[/tex]

[tex]2,122.64cm^{2} = \pi *r^{2}[/tex]

[tex]2,122.64cm^{2} = 3.14 * r^{2}[/tex]

[tex]\frac{2,122.64cm^{2} }{3.14} = r^{2}[/tex]

[tex]676cm^{2} = r^{2}[/tex]

[tex]\sqrt{676cm^{2} } = r[/tex]

[tex]26cm = r[/tex]

RESPUESTA:

     [tex]r = 26cm[/tex]
