Ok this is a fun little question.


So You are dealing with three sides of a right triangle. that means we can use Pythagorean's thm to solve for R


We know that A^2 + B^2 = C^2

r=A
36=B
r+12=C

r^2 + 36^2 =  (r+12)^2


Next simplify, r^2 + 1296 = r^2 + 24r + 144

1296-144 = 24r

1152=24r

48=r

It's an irrational number so that means it's value is virtually indiscernible. That's why it seems to go on forever but its most basic form is 3.14.

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.
