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.
