Radius plays a major role in determining the extent of an object from the center. Other terms associated with circle are sector and chord. The sector is a section of the circle that is made by two different radii. A chord is nothing but a line that joins two points on a circle. Diamet...
Theradiusis the length of a straight line from the center to any point on the outer edge. Thediameteris the length of a straight line from one edge to the opposite edge that passes through the circle’s center. It is equal to twice the length of the radius. ...
A circle is the set of all those points in a plane whose distance from the fixed point remains constant. The fixed point is called thecentreof the circle and the constant distance is known as theradiusof the circle. The line segment passing through the centre of a circle and having its ...
5.8cm is the length of largest chord of circle which is diameter. What is the radius of a equilateral triangle? The radius of a circumcircle of an equilateral triangle is equal to (a / √3), where 'a' is the length of the side of equilateral triangle. Does every triangle have an in...
Diameter of the circle =40 cm ∴ Radius (r) of the circle = 40/2 cm =20 cm Let AB be a chord (length = 20 cm) of the circle. In △OAB, OA = OB = Radius of circle = 20 cm Also, AB = 20 cm Thus, △OAB is an equilateral triangle. ∴θ=60^2
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
of the arc is, you can use it to determine the radius and size of the circle to which the arc belongs. This skill is useful for construction and engineering applications. Using the measurements derived from the arc's chord and the line bisecting it, you can determine the radius of an ...
The segment of a circle is the region between the chord and arc connecting the endpoints of the chord. A chord is a line segment that connects any two points on a circle. The segment would be the portion cut off of a sector if you sliced it at the point where the radius meets the ...
A point P is 26cm away from the centre O of a circle and the length PT of the tangent drawn from P to the circle is 10cm. Find the radius of the circle. 06:16View Solution How many tangent can a circle have ? 02:11View Solution Prove that in concentric circles, the chord of...
Use integration to find the circumference of the circle r = 2a \space cos \theta. Find the area A of a sector of a circle of radius R and angle \theta. Find the length of an arc and the area of the sector intercepted by a ...
