Option 3 : Either (I) or (II) and (III)

Let the radius of the circle be ‘r’ cm

Considering statement (I),

Circumference of circle = 2πr

⇒ 2 × 22/7 × r = 44

⇒ r = 7 cm

Considering statement (II) and (III),

Area of circle = area of rectangle = length × breadth

⇒ π r² = 14 × 11

⇒ (22/7) r² = 154

⇒ r² = 49

⇒ r = 7 cm

∴ The question can be answered using either (I) or (II) and (III)
