Multiply the diameter by pi, which is about 3.14.
Circumference=2diameter(pi) C=2(28)(pi) C=175.92918860102842135390802946365
pi*2r=cpi*d=cd=c/pidiameter=8.91267681
The diameter would be 28 cm.
pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
Circumference = pi*diameter = 87.96 inches.
Circumference of the circle: 28*pi inches
The circumference of a circle with a 28 unit diameter is: 88cir=dx22/7
The circumference of a circle with a diameter of 28 cm will be pi*28 cm which is approx 88.0 cm
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.
If the area of a circle is about 28 square inches the diameter of the circle is: about 6 inches (5.971).
The circumference of a circle with the radius of 28 inches is 175.9 inches. (C = r x 2 x Pi).
It is: pi*28 meters
Multiply the diameter by pi, which is about 3.14.
The diameter is 5.97 inches.
