Let us write multiples of 4 and 6 first,

4 : 4,8,12,16,20,24,28,…..

6: 6,12,18,24,30,36,42…..

From the above two expressions you can see, 4 and 6 have common multiples as 12 and 24. They may have more common multiple if we go beyond. Now, the smallest or least common multiple for 4 and 6 you can see here is 12. Therefore, 12 is the L.C.M of 4 and 6. Also, find to learn LCM of two numbers here.

Yogita Ingle 5 years, 7 months ago

Before discussing Euclid’s Postulates let us discuss a few terms as listed by Euclid in his book 1 of the ‘Elements’. The postulated statements of these are:

Assume the three steps from solids to points as solids-surface-lines-points. In each step, one dimension is lost.
A solid has 3 dimensions, the surface has 2, the line has 1 and point is dimensionless.
A point is anything that has no part, a breadthless length is a line and the ends of a line point.
A surface is something which has length and breadth only.

It can be seen that the definition of a few terms needs extra specification. Now let us discuss these Postulates in detail.

CSA of cone =πrl Given: area=88cm sq. Height= 14cm To find: diameter Solution: here height is slant height which means lenght =height So, CSA of cone =22/7*r*14 88=22/7*r*14 88=308/7*r 88*7/308=r 2cm= r So diameter is 4cm.
