Set up a ratio...6/18=x/27...reduce to 1/3=x/27...cross multiply and solve for x.
3x=27 so x=9

Answer:13years 7months 17 days
Step-by-step explanation:
1hr--->60min
116520hrs--->6.99120*10^6
convert hrs to days by dividing by 24
so you have 4855 days
divide it by 30 to get months which will be =161.833333 divide it by 12 to get yrs so you will get 13.48611111 then go ahead and subtract it to get the 13 years 7 months and 17 days
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

⇒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.
