Diameter of circle = 8.4 cm

radius = 8.4/2 = 4.2 cm

Circumference of circle = \bf{2πr}

= 2×22/7×4.2

= \bf{26.4 cm}

Therefore the circumference of the circle = \bf{26.4 cm}

diameter- 8.4 cm
Radius - 8.4/2 = 4.2
we know that, circumference of a circle is- 2πr.
2πr = 2(22/7).
so, the circumference of the circle is-
2*22/7 * 4.2 = 26.4 cm
