Draw $\overline{ AB }$ of length $9\, cm$. Draw $\odot( A, 3\, cm )$ and $\odot( B, 3.5\, cm )$. From the centre of each circle,draw tangents to the other circle. Write the steps of construction.

(N/A) Steps of construction:
$1$. Draw a line segment $\overline{ AB } = 9\, cm$.
$2$. With $A$ as the center,draw a circle of radius $3\, cm$. With $B$ as the center,draw a circle of radius $3.5\, cm$.
$3$. To draw tangents from $B$ to $\odot( A, 3\, cm )$:
a. Find the midpoint $M$ of $\overline{ AB }$ by drawing the perpendicular bisector of $\overline{ AB }$.
b. With $M$ as the center and $MA$ as the radius,draw a circle. This circle intersects $\odot( A, 3\, cm )$ at points $P$ and $Q$.
c. Join $BP$ and $BQ$. These are the required tangents from $B$ to the circle centered at $A$.
$4$. To draw tangents from $A$ to $\odot( B, 3.5\, cm )$:
a. With $M$ as the center and $MB$ as the radius,draw a circle (which is the same as the one drawn in step $3b$). This circle intersects $\odot( B, 3.5\, cm )$ at points $R$ and $S$.
b. Join $AR$ and $AS$. These are the required tangents from $A$ to the circle centered at $B$.
