Answer:

1.92cm

Step-by-step explanation:

Circumference of a circle is computed using the formula:

C=2\pi r

Where:

r = radius

π = 3.14

Since the radius is the distance of the center of the circle from any point of the circle and the diameter is the measure of a straight line that goes across the center of the circle from one side to the other, radius is half of a diameter. So the diameter = 2r.

We can then use the diameter to solve for the circumference by using the formula"

C = \pi d

So we just plug in what we know in the formula:

C = \pi d\\\\C = (3.14)(0.61cm)\\\\C = 1.9154cm\cong1.92cm

120 feet / 1 unit = 120 / 15 = 8 units

The dimensions of the drawing equates :

What is greater than 40 but less than 20
Paladinen [302]
I've already been complemented twice on my previous answer, but then I discovered that I mis-read the question.  My entire original answer was wrong, and I have to delete it.

I don't believe that any number can satisfy both of those conditions.
I'll say the question has no answer.
