Are of two concentric circles?

Find the length of the chord of the larger circle which touches the smaller circle. Complete step-by-step answer: The chord of the bigger circle touches the smaller circle, which means that the chord of the bigger circle is a tangent to the smaller circle. …

What is the radii of concentric circles?

Concentric circles always have the same center. The radius of two concentric circles is equal if both the circles lie on each other. The annulus is the region bounded by two concentric circles.

What is the space between two concentric circles called?

Concentric circles are circles with a common center. The region between two concentric circles of different radii is called an annulus.

How do you find the length of a chord in a concentric circle?

AB is the chord in a larger circle which touches a smaller circle at a point C. Now, we have to find the length of AB. Now, by using the theorem “the perpendicular drawn from the center of the circle bisects the chord”, we can express AB as, AB = 2AC. Hence, the length of the chord is $2\sqrt{{{a}^{2}}-{{b}^{2}}}$.

What are the 3 concentric circles of English?

The Three Concentric Circles Model represents the spread of the English language in terms of three concentric circles: the Inner Circle, the Outer Circle and the Expanding Circle (Kachru, 1985).

How is concentric calculated?

Q. What is the formula of concentric circle? Ans. The equation or formula is ( x – h )2 + ( y – k )2 = r12.

How do you find the radius of two concentric circles?

Similarly, the equation of a circle with centre at (h, k) and radius equal to r, is (x – h)2 + (y – k)2 = r2. Assigning different values to r1 we shall have a family of circles each of which is concentric with the circle (x – h)2 + (y – k)2 = r2.

How many radii are there in two concentric circles?

Ex 10.2, 7 – Two concentric circles are of radii 5 cm and 3 cm Ex 10.2,7 Two concentric circles are of radii 5 cm and 3 cm. Find the length of the chord of the larger circle which touches the smaller circle.

What is the length of the chord of the larger circle?

Since OP is the radius of the smaller circle to any chrod of the circle bisects the chord. hence the length of the chord of the larger circle which touches the smaller circle is 8cm. Was this answer helpful? The Fish Tale Across the Wall Tenths and HundredthsParts and Whole Can you see the Pattern?

Which point of a Circle bisects the chord?

Since, the tangent at any point of a circle is perpendicular to the radius through the point of contact. Since, the perpendicular from the centre of a circle to a chord bisects the chord. Please log in or register to add a comment.
