Question

The diameter of a wheel is 1.4 m, find its circumference

Answer 1

ans is 4.4 when we use formulae of 2pie r

Answer 2

hi nandit,

diameter of the wheel = 1.4m
so the radius = r =diameter / 2 = 1.4 / 2 = 0.7m

circumference = perimeter = 2πr
= 2 * 22/7 * 0.7
= 44 * 0.1
= 4.4 m

so the circumference of the given wheel is 4.4 m

Hope it helped
