191 I cateti di un triangolo rettangolo misurano rispetti- vamente 27 cm e 36 cm . Sapendo che il perimetro e 108 cm , calcola l'area e la misura dell'altezza re- lativa allipotenusa. [ \( 486 \mathrm{~cm}^{2} ; 21,6 \mathrm{~cm} \) ]

\begin{tabular}{l} 6.2. A cylinder has a radius of 7 cm and height of 10 cm . \\ \( \square \) \\ \hline \( .2 .1 \quad \) Calculate the volume of the cylinder. (if \( \pi=3,14 \) ) \end{tabular}

We desea eartriif una cala sin lapa y que almacene dial mayor volumen. para ello se dispone de una lamina d carton con las siguientes medidas. \[ 10 \mathrm{~cm} \times 9 \mathrm{~cm} \]

The coordinates of triangle ABC are \( \mathrm{A}\left(-4 \frac{1}{2},-2 \frac{1}{2}\right), \mathrm{B}\left(-4 \frac{1}{2},-1\right) \), and \( \mathrm{C}(6,-1) \). a. What is the distance between points A and B ? b. Give the coordinates for two points that are 4 units from point C . a. Points A and B are \( \square \) units apart. (Type an integer, fraction, or mixed number.)

a. Points \( A \) and \( B \) are 1.5 units apart. (Type an integer, fraction, or mixed number.) b. Give the coordinates of one point that is 4 units from point \( C \) in the x-direction. (Type an ordered pair.)
