Answer:
Circumference of circle= 37.68 units
Circumference of sector= 6.28 units
Step-by-step explanation:
The given figure is a circle with given radius OB= 6 units.
The circumference of a circle is the total length of its boundary.
For the complete circle its circumference can be calculated by;
Circumference= [tex]2\pi r[/tex]
[tex]=2*3.14*6\\=37.68[/tex] units
For the circumference of the Sector with 60° in the figure, the circumference can be calculate by:
[tex]=\frac{60}{360}* 2*\pi*6\\\\=\frac{1}{6}*12*3.14\\\\ =2*3.14\\\\=6.28[/tex] units
So, the circumference of the full circle is 37.68 units and the circumference of the sector is 6.28 units.
