A cuboid has total surface area of \( 86 \mathrm{sq} . \mathrm{m} \) and its lateral surface area is \( 32 \mathrm{sq} . \mathrm{m} \). Find the area of the base. Circular Cylinder

Give approximate answer to two decimal places. Evaluate \( \frac{76.514}{1+0.838 e^{-0.0293(70)}} \) \( \frac{76.514}{1+0.838 e^{-0.0293(70)}} \approx \square \).

Si \( A=\{2,3\} \) y \( B=\{1,4,5\} \), encontrar tres celaciones dejinidad de \( A \) en \( B \).
