A garden is circular with a border 3 m wide around it. The garden area alone is 379.94 m². What is the radius of the garden?
సమాధానం చూపించు & వివరణ
సమాధానం: (B) 11 m
వివరణ
πr² = 379.94 gives r² ≈ 121, so r = 11 m. (The stated total including the border is inconsistent, but the garden area fixes r.)
