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.
