The formula to calculate the circumference of a circle is C = 2πr = πD
D, the diameter of the circle is C - 105.
Therefore C = π (C - 105) = πC - 105π
πC - C = 105π : C(π - 1) = 105π
C = 105π/(π - 1)............as C = πD then
πD = 105π/(π - 1)
D = 105/(π - 1) = 49.03 ( to 2 decimal places)
The diameter of the circle is 49.03 cm
That's 41/2% less than the circumference of the circle.
The circumference of a circle is 3.14159… times, or pi times bigger than its diameter.

No. The ratio of circumference to diameter for any circle is pi, which is approx 3.14 Consequently, the circumference of every circle is more than 3 times greater than its diameter. but i think it is not applicable for curve surface.
Use the following formula to figure diameter when the circumference of a circle is known: Circumference = Pi x Diameter 20 = 3.1415927 x D D = 6.366
That's 41/2% less than the circumference of the circle.
Given a diameter d, the circumference of a circle is Pi*d. Thus the circumference is Pi times larger than the diameter.

The radius of a circle is always smaller than the diameter and the circumference.

The circumference is pi x diameter Perimeter of semi circle is (0.5) x pi x diameter + diameter which is diameter x (0.5pi + 1) Subtracting Perimeter from Circumference we get [pi x diameter] - [diameter x (0.5pi + 1)] which is diameter x [pi - 0.5pi -1] pi = 3.1415 Hence the result = diameter x (3.1415 - 1.570 - 1) which will always be positive. Hence circumference is greater than perimeter of semi circle. Intuitively also we see that the diameter is a straight line and the semi circles are arcs over the end points of the diameter.
113/pi feet ie less than half an inch under 36 ft
Yes, always
The circumference of any circle with a diameter of 12 inches is 12 (pi) = 37.7 inches (rounded) That's 4.72% more than 1 yard.
The circumference of the circle is larger than the perimeter of the rectangle.
