Question

The radius of a quarter circle is 3 millimeters. What is the quarter circle's perimete r=3 mm ude 3.14 for .. millimeters Submit can you explain

Answer 1

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:

`2r+(\pi r)/(2)`

So, the perimeter of the quarter circle:

`\begin{gathered} P=2r+(\pi r)/(2) \\ =2(3)+(3.14*3)/(2) \\ =6+4.71 \\ =10.71 \end{gathered}`

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