OpenStudy (sleepyhead314):

Area of a Circle = (pi) * (radius) * (radius) so first find the radius can you do that? :)

OpenStudy (anonymous):

Is the Radius 1 ?

OpenStudy (sleepyhead314):

yes

OpenStudy (sleepyhead314):

now plug that into the formula I gave

OpenStudy (anonymous):

So just 3.14 ?

OpenStudy (sleepyhead314):

mhmm and the unit is (yard) * (yard) = (yard)^2

OpenStudy (solomonzelman):

yes 3.14 yards^2

OpenStudy (solomonzelman):

the unit for area are squared, for volume are cubed... and 4th dimension doesn't exist (for us at least)
