Answer 2

Answer:

Circumference of the circle (C) = 26.4 cm

Explanation:

Given

radius of a circle (r)=4.2cm

________________________

we know that,

$\boxed {Circumference\: of\: a\: circle\:(C)\\\\=2\times\pi\times r }$

________________________

$C = 2\times \frac{22}{7}\times 4.2cm$

=$2\times 22 \times 0.6cm$

= $ 26.4cm$

Therefore,

Circumference of the circle (C) = 26.4 cm
