Explicación paso a paso:
[tex]Lado: L = 3cm[/tex]
[tex]Radio: r = 3cm[/tex]
[tex]\pi =3.14[/tex]
[tex]\alpha =90^{o}[/tex]
[tex]Perimetro: P = ?[/tex]
[tex]Area: A = ?[/tex]
Buscamos la longitud del arco:
[tex]C = \frac{2\pi r\pi \alpha }{360} = \frac{2\pi (3cm)(90)}{360} = \frac{540\pi cm}{360} =\frac{540cm(3.14)}{360} =\frac{1695.6cm}{360} = 4.71cm[/tex]
[tex]P = L+L+L+r +C[/tex]
[tex]P = 3cm + 3cm + 3cm+3cm+4.71cm[/tex]
[tex]P = 16.71cm[/tex]
Buscamos el área del cuadrado:
[tex]A_{1} =L^{2} =(3cm)^{2} = 9cm^{2}[/tex]
Buscamos el área del sector circular:
[tex]Asc = \frac{\pi r^{2}\alpha }{360} = \frac{\pi (3cm)^{2}(90) }{360} =\frac{\pi (9cm^{2} )(90)}{360} = \frac{810cm^{2}(\pi ) }{360} = \frac{810(3.14)cm^{2} }{360} =\frac{2544.69cm^{2} }{360}[/tex]
[tex]Asc = 7.07cm^{2}[/tex]
[tex]A = A_{1} +Asc[/tex]
[tex]A = 9cm^{2} +7.07cm^{2}[/tex]
[tex]A = 16.07cm^{2}[/tex]
RESPUESTA:
[tex]P = 16.71cm^{2}[/tex] [tex]; A = 16.07cm^{2}[/tex]
