Finding the Length of a Circle

To find the length of a circle when its radius is 5/n cm smaller than its diameter, we need to understand the relationship between the radius, diameter, and circumference of a circle.

The diameter of a circle is twice the length of its radius. So, if the radius is denoted as 'r', the diameter would be '2r'.

The circumference of a circle is given by the formula: C = 2πr, where 'C' represents the circumference and 'π' is a mathematical constant approximately equal to 3.14159.

In this case, the radius is 5/n cm smaller than the diameter. So, the radius can be expressed as '2r - 5/n'.

To find the length of the circle, we can substitute the value of the radius into the circumference formula:

C = 2π(2r - 5/n)

Now, let's simplify the equation and find the length of the circle.

Calculation

C = 2π(2r - 5/n)

Since we don't have the exact value of 'n', we can't provide an exact numerical answer. However, we can simplify the equation further.

C = 2π(2r - 5/n) C = 4πr - 10π/n

Therefore, the length of the circle, when its radius is 5/n cm smaller than its diameter, can be expressed as 4πr - 10π/n.

Please note that without the exact value of 'n', we cannot provide a specific numerical answer. However, the formula provided above represents the relationship between the radius, diameter, and circumference of the circle.

I hope this helps! Let me know if you have any further questions.
