Answer 2

$\underline \mathbb{SOLUTION}$

$\underline \mathbb{WE\:KNOW}$

$circumference \: of \: the \: cirlcle = 2\pi \times r$

$\underline \mathbb{ATQ}$

$= > 30.8 = 2 \times \frac{22}{7} \times r$

$= > 2 \times \frac{22}{7 } \times r = 30.8$

$= > r = \frac{30.8 \times 7}{2 \times 22}$

$= > r = \frac{308 \times 7}{2 \times 22 \times 10}$

$\underline \mathbb{HENCE\:ON\:SOLVING}$

$r = \frac{49}{10}$

$r = 4.9m$

$\underline \mathbb{ANSWER(r)=4.9m}$
