What happens to a chord when it leaves a circle?
It becomes a line intersecting the circle.
What happens if you triple the radius of a circle?
If you triple the radius of a circle . . . -- You should not expect anything to happen. Those around are likely to remain completely unaware that you have done anything to your circle. -- You wind up with a circle that's three times as big as it used to be. -- The diameter of the circle is three times the original diameter. -- The circumference of the circle is three times the original circumference. -- The area of the circle is nine times the original area.
How do you find radius of circle if you know the area?
The area of a circle is given by the equation A=πr2.To solve for r, divide both sides by π, then take the square root of both sides of the equation.This leaves you with the equation r=sqrt(A/π)
What fraction of the area of a circle of radius 5 lies between concentric circles of radius 3 and 4?
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
How do you find the radius of a circle only knowing the circumference?
The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.

What happens to a chord when it leaves a circle?

How do tornadoes swirl?
Tornadoes swirl because the storms that produce them rotate. Vertical wind shear is a condition in which there is a difference in wind speed and direction at different altitudes. If there is the right setup of wind shear, it can create horizontally rolling air currents. These currents can then be turned vertical by a thunderstorm updraft, inducing rotation within the storm. Under the right conditions, a portion of this rotation can tighten and intensify, producing a tornado.
Does a tornado have wind?
A tornado IS wind- very fast winds spinning in a circle.
