Step 1 We have to graph the plane curve defined by the parametric equations \(x=125 \cos t\ and\ y=125 \sin t\)

Step 2 The parametric equations defined by \(x=125 \cos\ t\ and\ y=125\)sintrepresents the equation of a circle with center at origin and radius 125. Now ,We graph the parametric equation defined by \(x=125 \cos\ t\ and\ y = 125\sin t, 0 \leq t \leq 2\pi\)
