Question

Two circles of radii $3cm$ and $2cm$, have their centres $9cm$ apart. Draw transverse common tangent and measure the length of the tangent and write the measurement.

Answer 1

First draw two circles of radii $r_1=3cm$ and $r_2=2cm$ with centres $P$ and $O$ respectively.

So, that the centres are $9cm$ apart from each other.

Draw the line joining two centres $O$ and $P$. And then draw the transverse common tangent.

Measuring the length of transverse common tangent using ruler, we get it as $7cm$
