A circle has a circumference of 120 meters. What is the measure of its radius? Round to the nearest tenth.

The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

Given that the circumference is 120 meters, we can solve for the radius by rearranging the formula, r = C/(2π).
Substituting the given value of C = 120 meters, we have r = 120/(2π) approximately equal to 19.1 meters rounded to the nearest tenth. Answer: \boxed{19.1}.
