    Let radius of the circle, r= 3.5cm and<div>

    π = 22/7

    Circumference of the circle= 2πr

    = 2 × 22/7 × 3.5

    = 2 × (22/7) × (35/10)

    = 2 × 11

    = 22 cm

    Area of the circle = πr²

    = 22/7 × (3.5)²

    = 22/7 × 3.5 × 3.5

    = 22 × 0.5 × 3.5

    = 38.5 cm²

    </div>
