Answer:

the  radius of the circle is 6cm

Step-by-step explanation:

the area of a circle is given to be  = 36πcm²

radius of the circle = ?

to find the radius of the circle lets start by applying  the formula for finding the area of a circle.

area of a circle = πr²

36πcm² = πr²

36π = πr²

divide both sides by π

36π/π = πr²/π

36 = r²

to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36

r² = 36

r =√36

r = 6cm

therefore the  radius of the circle is 6cm
