What is the ratio of radii of two circles at the center of which two arcs of the same length subtend angles 600 and 750?
Let r1 and r2 be the radii of the two circles and let their arcs of same length S subtend angles of 60° and 75° at their centres. ∴ r1 : r2 = 5 : 4.
What is the ratio of radii of two circles at the Centre of which two arcs of the same length?
θ=ar, where a is arc and r is radius. It is given, arcs of the circles are equal. So, ratio of radii of two given circles will be 7:3.
How do you find the ratio of two radii?
- Since it’s given that the ratio of the radii of two circles is 3:4 or 3/4, then we can write the following proportion:
- We know that the relationship between the radius r of a circle and the area A of a circle is given by the following formula:
- A =πr², where π is a universal, well-known constant.

What is the angle subtended in radians at the Centre of the circle by the chord if the length of a chord of a circle is equal to that of radius of the circle?
Therefore, angle subtended by the chord at a point on the major arc and the minor arc are 30° and 150° respectively.
What is radii of same arc?
Arcs of same radii means that the distance from a fixed centre (radius) is same on all the points and is equal for both the arcs , but it isn’t necessary that the length (perimeter) of the arcs are same .
What is the ratio of arc length to radius?
Conclusion. The ratio of arc length to radius length is the same in any two sectors with a given angle, no matter how big the circles are!
What is the ratio of the radius?
In its simplest form, the ratio of the circumference of a circle to its radius is two 𝜋 to one. For every one unit of radius, there is two 𝜋 units in the circumference.
Is radius equal to chord?
A chord of a circle is equal to the radius of the circle.
What is the ratio of radii of two circles?
The ratio of the radii of two circle is 5:3.
