Calculate the perimeter of quarter circle.

r = 2/√π

P = 2r(1+π/4)

= (4+π)/√π

≈ 4.0292121851

----------

1/4*Π*R^2=1>ΠR^2=4 R^2=(4/Π)>R=(2/√Π) P1=(Π/2)*R ,P2=2*R P=P1+P2=(Π/2)*(2/√Π)+2(2/√Π)=(Π/√Π)+(4/√Π)=(Π+4)/√Π units🍀❤🌻🌹🌷🌼🌸

1/4(3.1416)D²/4 = 1

R= 1.1284

1/4(2)(3.1416)(1.1284)

=1.77249072 = 1/4 perimeter

Perimeter = 1.77249072 + 2(1.1284)

=4.0293
