Uma esfera cuja superfície tem área igual \( 676 \pi \mathrm{~cm}^{2} \). Nessas condiçöes, determine: a) a medida do raio da esfera; a) o volume da esfera.

Graph the line containing the point \( P \) and having slope \( m \). \( P=(-6,3) ; m=0 \)

\( (-9,-1) \) and \( (12,14) \) Slope \( = \)

coordinate grid below. Find the coordinates of a fourth point o that the four points form the vertice of a rectangle.

Draw a graph of the line that contains the given point and has the given slope. \( (-5,0) ; m=\frac{1}{5} \)

Si \( P=(1,1) \) y \( Q=(2,2) \), la magnitud \( (|\overrightarrow{P Q}|) \) y dirección \( (\theta) \) del vector \( \overrightarrow{P Q} \) son, respectivamente
