Question

Find the circumference of a circle whose radius is-
(i) 35 cm
(ii) 4.2 cm
(iii) 15.4 cm​

Answer 1

$\bold{\red{Circumference= 2πr}}$

$\bold{(i)\:Circumference= 2×\dfrac{22}{\cancel{7}}×\cancel{35}}$

$\bold{Circumference= 220cm}$

$\bold{(ii)\:Circumference= 2×\dfrac{22}{\cancel{7}}×\cancel{4.2}}$

$\bold{Circumference= 26.4cm}$

$\bold{(iii)\:Circumference= 2×\dfrac{22}{\cancel{7}}×\cancel{15.4}}$

$\bold{Circumference= 96.8cm}$
