Answer 1

Answer:

$\red { Radius } \green {= 2.3 \:cm }$

Step-by-step explanation:

$Let \: d \: is \: the \: diameter \: of \: a \: circle$

$Circumference \: of \:the \: circle = 17.6 \:cm$

$\implies \pi d = 17.6$

$\implies \frac{22}{7} \times d = 17.6$

$\implies d = 17.6 \times \frac{7}{22}\\= 5.6 \:cm$

$Now, Radius (r) = \frac{d}{2} \\= \frac{5.6}{2} \\= 2.3 \:cm$

Therefore.,

$\red { Radius } \green {= 2.3 \:cm }$
