Let width = x, Therefore the length must equal 2x

Therefore insert these values on the sides of a rectangle.

Add: 2x + 2x + x + x = 18

Therefore 6x = 18

x = 3

The area of a circle is 9pi cm². Find its radius. <br>Please do this question with full solution:)

kirill115 [55]

Answer:

3 cm

Step-by-step explanation:

The formula for the area of a circle is:

$A = \pi r^2$

Where "r" represents the radius of the circle. We can substitute the given value for Area into the equation to solve for the radius.

<h3>Solve for Radius</h3>

$A=\pi r^2\\9\pi = \pi r^2$

Divide both sides by π

$9=r^2$

Take the square root of both sides

$\sqrt9=\sqrt {r^2}\\r=3$

The radius of the circle is 3 cm.
