Question

Find the circumference of this figure. Show your calculations.

Answer 1

Circumference of circle= 37.68 units

Circumference of sector= 6.28 units

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=
`2\pi r`

`=2*3.14*6\\=37.68` units

For the circumference of the Sector with 60° in the figure, the circumference can be calculate by:

`=(60)/(360)* 2*\pi*6\\\\=(1)/(6)*12*3.14\\\\ =2*3.14\\\\=6.28` units

So, the circumference of the full circle is 37.68 units and the circumference of the sector is 6.28 units.
