    Given:

    • Circumference of circle = 8π

    To find out:

    Find the diameter of circle?

    Formula used:

    Circumference of circle = 2πr

    Solution:

    Circumference of circle = 2πr

    ⇒ 8π = 2πr

    ⇒ r = 8π/2π

    ⇒ r = 4 cm

    Now,

    Diameter = 2 × Radius = 2 × 4 = 8 cm
