See explanation.

If the diameter is $2 y d$ $2yd$ then the radius is $r = \frac{d}{2} = 1 y d$ $r=d/2=1yd$

Now the area is:

$A = π \times r^{2}$ $A=pixxr^2$

$A = π \times 1^{2} = π$ $A=pixx1^2=pi$

The circumference is:

$C = 2 π \times 1 = 2 π$ $C=2pixx1=2pi$

Answer:

The area is $A = π$ $A=pi$ square yards, and the circumference is $C = 2 π$ $C=2pi$ yards.
