Answer 1

$\underline\mathfrak{Ans.}$ $\frac{900}{π}$m

$\underline\mathfrak{Explanation}$

Circumference = 2πr -----(i)

Speed = $\frac{Distance}{Time}$

Putting the Values

10 m/s = $\frac{3x m}{9 mins}$

10 × 9 × 60 = 3x

$\frac{5400}{3}$ = x

x = 1800

Putting value in eqn (i)

2πr = 1800

r = $\frac{1800}{2π}$

r = $\frac{900}{π}$

Hope it helps!
