Answer:
The lcm is 84
Step-by-step explanation:
3: 3,6,9,12,15,18,21,24,27,30,33,36,39,41,44,47.........84
4: 4,8,12,16,20,24,28,32,36,40,44........84
7: 7,14,21,28,35,42.......84
Answer: The answer is 7.
e
The length of metal band around the given clock is 50. 24 cm.
Here, the diameter of given clock = 16 cm
Now, Diameter = 2 x Radius
So, Radius = D/2 = 16 cm/2 = 8 cm
⇒The radius of the clock = 8 cm
Now, The metal Band around it = The CIRCUMFERENCE of the watch
Circumference of the clock = 2 π r
= 2 x ( 3.14) x ( 8) = 50.24 cm
or, C = 50.24 cm
Hence, the length of metal band around the given clock is 50. 24 cm.
3
is the answer
because sprt - sprt = 0
then 5-2=3
