The circumference of a circle whose radius is 9x sq. is

True [87]

<h3>The circumference of circle is $56.52x^2$ units</h3>

Solution:

Given that,

Radius of circle = $9x^2$ units

To find: circumference of circle

The circumference of circle is given as:

$C = 2 \pi r$

Where, r is the radius of circle

Substitute, r = $9x^2$

$C = 2 \times 3.14 \times (9x^2)\\\\C = 6.28 \times 9x^2\\\\C = 56.52x^2$

Thus circumference of circle is $56.52x^2$ units
