a circle has a circumference of 110.6mm

find diameter to the nearest tenth
A.35.2mm
b.36.2mm
c.37.2mm
d.38.2mm

C = pi * d

so it c

You already know c which is the circumference.

To find the diameter, use this formula:

d = C / pi

what do you mean i don't get it

diameter = 110.6 / 3.14

d = ?

Right.

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

Circumference = π * diameter

Given that the circumference is 110.6mm, we can substitute this value into the formula:

110.6 = π * diameter

To find the value of π, we can use an approximation of 3.14.

110.6 = 3.14 * diameter

Now, we can solve for the diameter:

diameter = 110.6 / 3.14
diameter ≈ 35.2mm

Therefore, the diameter of the circle is approximately 35.2mm.

So, the correct answer would be A. 35.2mm.
