What is the diameter of a circle with a 6.7 cm circumference?

Answer 1

Aurora Ayala

You use the circumference formula:

#d=2.133#

The circumference is equal to #2π*r# where #r# is the radius, which is equal to half the diameter #d#. So we have:

#6.7=2*π*r#

#r=d/2#

Substituting the 2nd equation to the 1st gives:

#6.7=2*π*d/2#

#6.7=π*d#

#d=6.7/π=2.133#

To find the diameter of a circle when given the circumference, you can use the formula:

diameter = circumference / π

Given the circumference (C) of 6.7 cm, we can plug it into the formula:

diameter = 6.7 cm / π

Using the value of π (pi), which is approximately 3.14159, we can calculate:

diameter ≈ 6.7 cm / 3.14159 diameter ≈ 2.13 cm

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
