33) What can be the length of the missing side? 12 and 10

Calculate the area of a circle with a radius of 5 m using \( \pi \\).

Determine o valor de \( m \) para que as retas \( r \) e \( s \) sejam concor- rentes e ache o ponto de interseção, sendo \( r: \frac{x-1}{3}=y+2=\frac{z}{-2} \quad \) s: \( \left\{\begin{array}{l}x=m-t \\ y=1+t \\ z=2 t, t \in R\end{array}\right. \)

Find the midpoint of the line segment with the given endpoints. \( \begin{array}{ll}\text { 23) }(-7,10),(-10,-10) \\ \mathrm{mPX}=-7+-10^{2} & \text { 24) }(-1,-6) \cdot(6,-5)\end{array} \)

\begin{tabular}{|l|}\hline Find the distance between the two points. (Show Work) (Page 31-33, 36) (3pts) \\ \hline\( d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}} \) \\ \( P(-12,-23) \) and \( Q(6,1) \)\end{tabular}

3. Déterminer le centre \( M \) et le rayon \( r \) du cercle \( \mathcal{C} \) donné par l'intersection de la sphère d'équation \( \mathcal{S}: x^{2}-6 x+y^{2}-2 y+z^{2}-18 z=-42 \) et du plan \( \Pi: 4 x-y+4 z=14 \).
