Solution

The correct option is A $42$ m
Distance travelled in $600$ steps $=$ $44$ $\times$ $600$ = $26400$ $m$ 4

Circumference of pond $=$ $26400$ $c m$

$\Rightarrow 2 π r = 26400 \Rightarrow r = \frac{26400 \times 7}{2 \times 22} = 4200 c m = 42 m$

Therefore, radius of pond is $42$ $m$ .

The correct option is A 42 mDistance travelled in 600 steps = 44 × 600 = 26400 m4Circumference of pond = 26400 cm⇒2πr=26400⇒r=26400×72×22=4200cm=42mTherefore, radius of pond is 42m.
