Question

If the diameter of the circle is 5.6cm find its circumference​

Answer 1

Answer:

Diameter = 5.6cm

$\sf{Circumference} = \sf{2πr} = \sf{πd}$

Circumference = 17.6cm

Answer 2

Answer:

Circumference of a circle=$2\pi r$

Radius of the circle=5.6/2=2.8 cm

value of π=22/7 or 3.14(Normally take 22/7)

Circumference of this circle=2πr

=2*22/7*2.8

=17.6 cm
