“Circumference of a circle is twice the radius” a) True b) False<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The statement “Circumference of a circle is twice the radius” is False<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To understand why this statement is false, we need to review the formula for the circumference of a circle in terms of its radius.<\/p>\n\n\n\n

Formula for Circumference:<\/h4>\n\n\n\n

The circumference ( C ) of a circle is the distance around the edge of the circle, and it is given by the formula:<\/p>\n\n\n\n

[
C = 2 \\pi r
]<\/p>\n\n\n\n

where:<\/p>\n\n\n\n

    \n
  • ( C ) is the circumference,<\/li>\n\n\n\n
  • ( \\pi ) (pi) is a mathematical constant approximately equal to 3.14159,<\/li>\n\n\n\n
  • ( r ) is the radius of the circle.<\/li>\n<\/ul>\n\n\n\n

    According to this formula, the circumference of a circle is twice the product of ( \\pi ) and the radius<\/strong>. Thus, rather than being simply “twice the radius,” the circumference is twice the radius multiplied by ( \\pi )<\/strong>.<\/p>\n\n\n\n

    Why the Statement is False:<\/h4>\n\n\n\n

    The radius (( r )) is the distance from the center of the circle to any point on its edge. If the circumference were simply twice the radius, the formula would look like ( C = 2r ). However, this would omit the important factor of ( \\pi ), which accounts for the circular shape of the circumference.<\/p>\n\n\n\n

    In other words:<\/p>\n\n\n\n

      \n
    • If a circle has a radius of 1 unit, then its circumference would be ( 2 \\pi \\approx 6.28 ) units, not 2 units.<\/li>\n\n\n\n
    • The circumference is always larger than twice the radius by a factor of ( \\pi ).<\/li>\n<\/ul>\n\n\n\n

      Correct Interpretation:<\/h4>\n\n\n\n

      The circumference of a circle is approximately 6.28 times the radius<\/strong> because ( 2 \\pi \\approx 6.28 ). This reflects the actual relationship between a circle\u2019s circumference and its radius, making the given statement incorrect.<\/p>\n\n\n\n

      In summary, the correct answer to the question is “False,” because the circumference of a circle is not merely twice the radius but rather ( 2 \\pi ) times the radius.<\/p>\n","protected":false},"excerpt":{"rendered":"
