The circumference of a circle divided by its own diameter will leave you with pi which is about 3.142 correct to three decimal places.
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
Circumference = (pi) x (diameter) = 14 pi = 43.9823 inches (rounded)
Well to do this you have to master the art of algebra :) C= π (pie) x Diameter Diameter= Circumference/π (pie) (C divided by Pie)..........we need to have D on its own so we do the opposite of multiply on the pie to get diameter on its own. ∴ D= C/π (pie)
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
circumference/pi = diameter
circumference = pi*100mm
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
Either pi times the diameter or pi times twice the radius (which is the diameter)
Circumference = (pi) x (diameter) = 14 pi = 43.9823 inches (rounded)
What is 27 X 3.14? 27 pi
Well to do this you have to master the art of algebra :) C= π (pie) x Diameter Diameter= Circumference/π (pie) (C divided by Pie)..........we need to have D on its own so we do the opposite of multiply on the pie to get diameter on its own. ∴ D= C/π (pie)
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
Just over 25' ( 8 x pi)
19 pi, ie 19 x 3.1415 = 59.69
39 inches / pi = 12.4 inches
