Answer:
Let O be the common center of two concentric circles and let AB be a chord of larger circle touching the smaller circle at P join OP
Since OP is the radius of the smaller circle to any chrod of the circle bisects the chord.
∴ AP=BP
In right ΔAPO we have
OA
2
=AP
2
+OP
2
⇒25−9=AP
2
⇒AP
2
=16⇒AP=4
Now AB=2,AP=2×4=8[∵AP=PB]
hence the length of the chord of the larger circle which touches the smaller circle is 8cm.

Answer:
true
Step-by-step explanation:
idek
price of cycle = 3600 Rs
if the price is reduced by 20%, the price will be:
3600 - (20/100*3600) = 3600 - (20*36)
= 3600 - 720
= 2880 Rs
if the price is further reduced by 1/4 (25%),
2880 - (25/100*2880) = 2880 - 720
= 2160 Rs
Therefore, if the price is reduced first by 20% and this is further reduced by 25%, the final price after reduction will be 2160 Rs.
