If `d_1,d_2` (d_2>d_1) be the diameters of two concentric circles and c be the length of a chord of a circle which is tangent to the other circle prove that `d_2^2=c^2+d_1^2`

If d_(1) and d_(2) (d_(2) gt d_(1)) be the diameters of two concentric circles and c be the length of a chord of a circle which is tangent to the other circle, prove that d_(2)^(2)=c^(2) + d_(1)^(2) .

If d_(1), d_(2) (d_(2) gt d_(1)) be the diameter of the two cocentric circles and c be the length of a chord of a circle which is tangent to the other circle, prove that d_(2)^(2)=c^(2)+d_(1)^(2) .

If radii of the two concentric circles are 15cm and 17cm, then the length of each chord of one circle which is tangent to other is: 8cm (b) 16cm (c) 30cm (d) 17cm

If radii of the two concentric circles are 15cm and 17cm, then the length of each chord of one circle which is tangent to other is: 8cm (b) 16cm (c) 30cm (d) 17cm

If radii of the two concentric circles are 15cm and 17cm, then the length of each chord of one circle which is tangent to other is: 8cm(b)16cm(c)30cm(d)17cm

If D is thedaneter of the brger circle and d the diameter of the small circle then D+d=?
