Circumference = 2 x PI x radius = 28 x PI = (approx) 87.9645943"
Circumference of the circle: 28*pi inches
Circumference = pi*diameter = 87.96 inches.
Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.
You divide the diameter by two to get the radius (28 / 2 = 14)
The circumference is 175.92918860102841 feet.
Circumference = 2 x PI x radius = 28 x PI = (approx) 87.9645943"
Circumference of circle: 28 times pi inches
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
Circumference of 14 inch radius circle: 2*pi*14 = 28*pi inches or about 87.96 inches rounded to two decimal places
Circumference of the circle: 28*pi inches
pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units
Circumference = pi*diameter = 87.96 inches.
Formula of Circumference = 2πr 2πr = 28π 2r = 28 r = 14 The radius is 14
Thee formula for the circumference of a circle should read 2*pi*radius or pi*diameter. In which case using either formula its circumference is 88 inches rounded.
