A = 38.52 cm2
Circumference of circle: 2*pi*36 = 226.195 cm rounded to 3 decimal places
you multiply the diameter by pi which is approximately 3.14
C = 28.274 yd
What is the sum of a center angles of a circle
2yd x 2 x pi = 12.566 yd
We will never know
Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.
1 acre = 4840 sq yd → 1½ acres = 1½ × 4840 sq yd = 7260 sq yd area circle = π × radius² → radius = √(area_circle ÷ π) = √(7260 sq yd ÷ π) ≈ 48.072 yd
Using 3.14 as Pi the area of circle is: 55.3896
Using 3.14 as Pi the area of circle is: 216.31460000000007
