Please answer this correctly

Area of a full circle is pi x R^2

Find the radius:

Area of the circle given = 0.785 x 4 = 3.14

3.14 = 3.14 x r^2

R^2 = 1

R = sqrt(1)

R = 1 cm

Diameter = r x 2 = 2 cm

Circumference = 3.14 x 2 = 6.28

I/4 of circumference = 6.28/4 = 1.57

Perimeter = 1.57 + 1 + 1 = 3.57 cm.

i answerd and just got 10pts

no hate

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
