Tangents ..... are parallel under conditions you gave. A tangent to a circle is perpindicular to the radius (diameter) at the point of contact. 2 lines perpindicular to the same line are parallel.
They're equal, 12 cm long.
Circumference of a circle divided by pi is equal to the circle's diameter.
The circumference of a circle divided by its diameter is equal to pi which is an irrational number.
the diameter of a circle is defined by the largest length from one side of the circle to the other side of the circle. the area of a circle is equal to pi(3.14) times the radius squared. the radius is equal to half of the diameter.
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
Approximately yes. Circumference is equal to pi times the diameter of the circle, which is 3.14159 times the diameter.
The circumference of a circle divided by its diameter is equal to the value of pi.
The largest diameter you can inscribe in a circle is a square. The square's diagonal is equal to the diameter of the circle; the length of the side of the square is therefore equal to the circle's diameter, divided by the square root of 2.
No, the radius of a circle is always 1/2 of the diameter.
The diameter of the circle is 11.997 units.
it would be the diameter of the smaller circle times sqrt 2
