Question

the area of a circle is 36 pie cm^2 what is the radius of the circle?

Answer 1

Answer:

6cm

Step-by-step explanation:

To break down the steps back to radius, the formula is placed reversely in $\pi r^{2}$

Since 36 is without pie, square root is needed.

$\sqrt{36}$=6

Therefore, 6 cm is the radius.

Answer 2

Answer:

Step-by-step explanation:

hello :

the area is : A=πr²    r :  the radius

36π = πr²   means : r²=36      so : r= 6
