Answer 2

Answer:

The radius is 10cm

The radius is 10cmThe distance be dcm

The radius is 10cmThe distance be dcmThe length of chord is 12=2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6=

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d 2 d

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d 2 d 2

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d 2 d 2 =64

The radius is 10cmThe distance be dcmThe length of chord is 12=2 r 2 −d 2 6= 100−d 2 36=100−d 2 d 2 =64d=8cm
