El área de un círculo es: pi * radio al cuadrado.
$${\mathtt{A}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{r}}}^{{\mathtt{2}}}$$
El radio es la mitad del diámetro, y el diametro es 2.
Entonces,
r = 1
$${\mathtt{A}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{1}}}^{{\mathtt{2}}}$$
$${\mathtt{A}} = {\mathtt{\pi}}$$
A = 3.14 cm2
La circunferencia de un círculo es: pi * diametro.
$${\mathtt{C}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{d}}$$
$${\mathtt{C}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}$$
C = 6.28 cm
