Assuming the shape is a cube, it would be 2*2*2 = 8 cubic units
A unit circle is a circle with radius equal to one.
A = pi r2A = 3.14 x 82A = approximately 200.96 square units
The formula for circumference is 2(pi)r.Plug the numbers into the formula.You get (2)(pi)(4).8(pi) or, assuming pi is 3.14, 25.12.
You would need to include the radius to be able to determine the area.
