What is the radius of 5.2cm circle?

Answer 1

The radius of a circle is the distance from the center of the circle to any point on the circle itself. In this case, the radius of a 5.2cm circle would be 5.2cm. This measurement is constant regardless of where the measurement is taken on the circle.

Answer 2

if 5.2 cm is circumference, then r = 5.2 / (2 * pi)= 0.828 cm

if 5.2 is area, then r = sq. root (area / pi) = 1.286 cm
