Sagot :

Given:

The radius of the quarter circle is given 3 mm.

To find:

The perimeter of the quarter circle.

Solution:

It is known that the perimeter of the quarter circle is given by:

[tex]2r+\frac{\pi r}{2}[/tex]

So, the perimeter of the quarter circle:

[tex]\begin{gathered} P=2r+\frac{\pi r}{2} \\ =2(3)+\frac{3.14\times3}{2} \\ =6+4.71 \\ =10.71 \end{gathered}[/tex]

Thus, the perimeter of the quarter circle is 10.71 mm.
