Answer 3

It's 1/4 of a circle..just act like it's a whole circle and find the perimeter.

Answer 4

\(P = 2 \pi r\)

Answer 5

\(P = 2(3.14)(3)\)

Multiply 2 * 3.14 * 3

Answer 6

So the length of an arc is equal to
\[length = \frac{ n }{ 360 } * 2 \pi r\]
n being the angle

so \[\frac{ 90 }{ 360 } * 2 \pi (3)\]
\[\frac{ 1 }{ 4 } * 6\pi\]
\[\frac{ 3\pi }{ 2 }\]
