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

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
