Option C:
Perimeter of the
of a circle = 10.71 cm
Solution:
Given figure is
of a circle.
It is a quarter of a circle.
Radius = 3 cm, Value of <em>π</em> = 3.14
To find the perimeter of the quarter of a circle.
Perimeter of the quarter of a circle formula: ![$\frac{\pi r}{2}+2r](https://tex.z-dn.net/?f=%24%5Cfrac%7B%5Cpi%20r%7D%7B2%7D%2B2r)
![$\text {Perimeter} =\frac{\pi r}{2}+2r$](https://tex.z-dn.net/?f=%24%5Ctext%20%7BPerimeter%7D%20%3D%5Cfrac%7B%5Cpi%20r%7D%7B2%7D%2B2r%24)
![$=\frac{3.14\times3}{2}+2\times3$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B3.14%5Ctimes3%7D%7B2%7D%2B2%5Ctimes3%24)
![=4.71+6](https://tex.z-dn.net/?f=%3D4.71%2B6)
Perimeter of the quarter of a circle = 10.71 cm
Option C: 10.7 is the correct answer.
Hence perimeter of the
of a circle is 10.71 cm.
