The radius of the given circle with a central angle of 7π/10 and arc length of 33cm is 15cm.
It is given that
The central angle of the given circle = 7π/10 radians
Length of arc = 33cm
Arc length = central angle* radius
From the above formula
Radius = Arc length/Central Angle
Radius = [tex]\frac{33}{(7\pi)/10 }[/tex]
Radius = 15cm
Therefore, radius of the given circle is 15cm.
