Question

what is the diameter of a circle of circumference 1256 m

Answer 1

if c=1256
2pie .r = 1256
r=1256×7/22×1/2
r=
$1256 \times 7 \div 22 \times 1 \div 2$

Answer 2

circumference of circle=2πr
                           1256=2×22÷7×r
                          r=(1256×7)÷2×22
                         r=57.09m
 diameter=114.18m
