 Question from F, a student: How do you find the area of a circumference of 6? Thanks.

Hi,

I assume have a circle with a circumference of 6 units. Do you know the expression for the circumference of a circle of radius $r?$ If so set the circumference to 6 units and solve for $r.$ Do you know the expression for the area of a circle of radius $r?$
