Divide a circle of radius $3$ cm into eight equal parts.

Open in App

Solution

To divide the circle into $8$ parts where radius of circle $= 3 c m$
Circumference $= 2 π r$
$= 6 π$
Hence cut lengths of $\frac{6 π}{8}$ to divide in $8$ equal parts.
or
Draw the circle , then cut $\frac{2 π}{8}$ angles from a fixed diameter line.
