There are many pairs that are solutions to this inequality. You can find them all by graphic this on a coordinate plane and then shading the region. 

You can also plug any of the ordered pairs that they give you into the equation and see if they produce a true statement.

Para armar un escritorio, Eduardo tendrá que usar 20 tarugos, los que debe cubrir completamente con una capa de pegamento. Él ca
Degger [83]

El área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento.

<h3>Como determinar si la superficie cubierta por el pegamento es suficiente</h3>

En esta pregunta debemos calcular el área superficial total de los tarugos (A_{s}), en milímetros cuadrados, y comparar el resultado con la cifra afirmada por Eduardo. El área superficial total es:

A_{s} = 20\cdot \pi\cdot (5\,mm)^{2}\cdot (80\,mm)

A_{s} \approx 125663.706\,mm^{2 }

En consecuencia, el área superficial total de los veinte tarugos es mayor que el área superficial cubierta por el pegamento. Francisca tiene la razón. \blacksquare

<h3>Observación</h3>

El enunciado omite las dimensiones <em>geométricas</em> de cada tarugo (5 milímetros de radio y 80 milímetros de longitud).
