Circumference = pi*30 = 94.248 inches rounded to 3 decimal places
Area = pi*152 = 706.858 square inches to 3 decimal places
Diameter Diameter radius
diameter times pi(3.14159) equals cicumference
Divide the diameter by 2.
If 20 is the diameter, the circumference is 62.8 yards.
diameter. a radius doesn't even run through a circle. a circumference is the line that surrounds the circle.
The cicumference of any circle divided by its diameter is aways equal to pi.
Cicumference = π*d = 56.55 units
circumference = π x diameter ⇒ diameter = circumference ÷ π = 32 in ÷ π ≈ 10.19 in
circumference of a circle = pi*diameter or 2*pi*radius cicumference = 62.83185307 or 63 feet to the nearest foot
pi=3.14 it is really long # but we shorten is to 3.14. 3.14 times the diameter
Circumference of circle when pi is 3.14: 2 times 3.14 = 6.28 units
half of a diametre is radius. hence multiply the diameter by 0.5 then use the formular of cicumference, which is 2*pie*r
