The circumference of the circle is calculated through the equation, C = 2πr. From this, the radius is calculated by,
r = C / 2π
Substituting the known values,
r = 8π /2π = 4
The area of a circle is,
A = πr²
Substituting,
A = π4² = 16π units²

The circumference of a circle is 8pi inches. Find its radius and area.
