Sagot :

belcatya
formula of circle's area is S=πr²
so 36π=πr²
r²=36
r=6
diametr d=2r, r- radius
so d=2*6=12
Answer: C 12
A= r^2 x pi the coefficient of pi is the radius squared so, take the square root of 36 which is 6 to get the radius and times it by 2 to get the diameter answer is C 12 hope this helps
