Question

# In a circle of radius $$6$$ cm, a chord of length $$10$$ cm makes an angle of $$110$$ $$^{\circ}$$ at the center of the circle. Find the circumference of the circle.

Solution

## $$\Rightarrow$$  $$r=6\,cm$$$$\Rightarrow$$  Circumference of the circle $$=2\pi r$$$$\therefore$$  Circumference of the circle $$=2\times 3.14\times 6$$$$\therefore$$  Circumference of the circle $$=37.68\,cm$$Mathematics
