the area of a circle is 9 pie square meters. What is the radius of the circle? What is the circumference of the circle?

Thank you for the opportunity to help you with your question!

area of circle = pie* (radius)^2

area of circle given as 9 pie,so

9 pie = pie* (radius)^2

9 = (radius)^2

radius = 3

circumference = 2* pie*radius

= 2*pie*3

= 6 pie

= 6 π

radius of circle = 3

circumference of circle = 6 π = 6 pie
