The radius of a circle is 10. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
The circumference of a circle is given by the equation:
C = 2πr
The diameter of a circle is given by the equation:
d = 2r
So, the ratio of the circumference of the circle to the circle's diameter can be expressed as:
C/d = (2πr)/(2r) = π
Of course!
Given that the radius of the circle is 10, the diameter would be:
diameter (d) = 2 * radius (r)
d = 2 * 10
d = 20
The circumference of the circle is given by the formula:
Circumference (C) = 2πr
C = 2π * 10
C = 20π
Therefore, the ratio of the circumference of the circle to the circle's diameter is:
C/d = 20π / 20
C/d = π
Therefore, the ratio of the circumference of the circle to the circle's diameter is π.
IF THIS ANSWER IS WRONG I SWER I WILL REPORT THE HECK OUT OF THIS SITE AND GET IT TAKEN DOWN
I apologize if my response was not clear. Let me clarify:
Given that the radius of the circle is 10, the diameter would be:
d = 2r
d = 2*10
d = 20
The circumference of the circle is given by the formula:
C = 2πr
C = 2π*10
C = 20π
Therefore, the ratio of the circumference of the circle to the circle's diameter is:
C/d = (20π) / 20
C/d = π
Therefore, the ratio of the circumference of the circle to the circle's diameter is π.
