Answer 2

$Let \: the \: radius \: of \: a \: wheel = r \: cm$

$Circumference \:of \: the \: wheel = 62.8 \:cm$

$\implies 2\pi r = 62.8$

$\implies 2 \times \frac{22}{7} \times r = 62.8$

$\implies r = 62.8 \times \frac{7}{44}$

$\implies r = 9.990 \: cm$

Therefore.,

$\red{ Radius \: of \: the \: wheel }\green { = 9.990 \: cm }$
