Suppose that the area between a pair of concentric circles is 49pi. find the length of a chord in the larger circle that is tangent to the smaller circle.

14 units

Step-by-step explanation:

We are given that the area between two concentric circles is

We have to find the length of chord in the larger circle that is tangent to the smaller circle.

Let be the radius of two circles.

be the radius of small circle and be the radius of large circle

We know that area pf circle=

Area of large circle =

Area of small circle =

Area between two circles =

Area of large circle -Area of small circle=

By pythagorus theorem

Length of chord=

Hence, the length of chord of the larger circle = units
