Determine the diameter of a circle if its length is 13.4 cm.
The circumference is found by the formula l = 2 пR or l = п D, where P is a constant equal to 3, 14; D is the radius.
From here we express the diameter: D = l / п.
Substitute the data into the formula and get.
D = 13, 4/3, 14.
D = 2, 3 cm.
Answer: the diameter of the circle is 2.3 cm.
