Answer:

3.14d > 50 cm

Explanation:

Given that the circumference of a circle is approximately 3.14 times the length of its diameter

If the circumference is C and the length of the diameter is d then

C = 3.14d

If the circumference of a circle is more than 50 cm then

3.14d > 50

The inequality can be used to find all possible diameter lengths, d,

d > 50/3.14

d > 15.92cm
