Answer:

r= d/2 => 12/2 => 6

a= πR²

a= 3.14×{6}²

a= 113.04 square yard (yd²)

or

a= 94.51 m²

Answer:

37.68 yards

Step-by-step explanation:

The diameter of a circle is 12 yards. What is the circle's circumference?

Use 3.14 for ​.

Use this formula to find the circumference from the diameter.

C =​ d

Use 3.14, approximation for ​.

​ ≈ 3.14

The diameter is 12 yards. Replace d by 12 in the formula.

C = ​d

SOLVE:

=  3.14 x 12

=  37.68

The circumference is about 37.68 yards.
