A circle has a radius of 12 in Find the diameter of the circle?
diameter is 2 times the radius 24
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Formula for the radius of a circle?
Well to find the radius it is diameter/2.
How do you find radius of circle?
Measure the distance from the centre of the circle to its circumference.
What is the formula to find a radius of a half circle?
same as for a whole circle
How can you find the direction of particle at a given time if the particle is moving in circle?
The direction of a particle moving in a circle at a given time can be found by determining the tangent to the circle at that point. The tangent is perpendicular to the radius of the circle at that point and indicates the direction of motion.
How do you find the tangent of a circle?
a tangent is a line that touches the circle at only ONE point
How do you find the normal and tangent of a circle?
The link below gives the equations for the line that tangent. Once you have that, finding the normal should be straightforward.http://mathworld.wolfram.com/CircleTangentLine.html
Does a trigonometry tangent relate to a circle's tangent?
A circle's tangent is exactly the same as a triangle's tangent. If you look at a circle, you can make the radius the hypotenuse. Then make a vertical line from the point, and a horizontal line from the center. If you look, you have a triangle made inside the circle. This is why angles can be measured in radians, a unit that is derived from the circumference of a circle.-------------------------------------------------------------------------------------------By doing a little calculus, we find that the slope of the equation of a circle-the slope of the tangent line-is given by the tangent of an angle.AnswerEverything written above is correct, but doesn't have anything to do with tangents (in the circle sense of the word). Suppose you're given an angle theta. Draw a circle together with two radii, one horizontal and the other at an angle theta from the first one. (So far, this is the same as above.) Now draw the tangent to the circle at X, the point where the non-horizontal radius meets the circumference. Let Y be the point where this tangent meets the horizontal line through the centre. Then, assuming the radius is 1, tan(theta) is the distance XY, which is the length of part of the tangent.
How do you find the length of a radius drawn from the center of the circle to a tangent?
It is the same length from the centre to any point on the circumference so just measure it
Which construction uses the compass for only one step in addition to drawing the circle itself?
The construction that uses the compass for only one additional step, aside from drawing the circle, is the construction of a tangent to a circle from a point outside the circle. In this process, the compass is first used to draw the circle, and then it is used again to find the point where the tangent line touches the circle, typically by constructing a radius to that point and creating a right triangle to determine the tangent's direction.
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
How do you find the director circle of circle?
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
How do you find the radius of a circle if you know the radius?
You already know the radius.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find what a diameter of a circle is?
It is twice the radius of a circle
