Hello Buddy!
Answer ⬇⬇⬇
A micelle an aggregate (or supramolecular assembly) of surfactant molecules dispersed in a liquid colloid. A typical micelle in aqueous solutionforms an aggregate with the hydrophilic"head" regions in contact with surrounding solvent, sequestering the hydrophobic single-tail regions in the micelle centre. This phase is caused by the packing behavior of single-tail lipids in a bilayer. The difficulty filling all the volume of the interior of a bilayer, while accommodating the area per head group forced on the molecule by the hydration of the lipid head group, leads to the formation of the micelle. This type of micelle is known as a normal-phase micelle (oil-in-water micelle). Inverse micelles have the head groups at the centre with the tails extending out (water-in-oil micelle). Micelles are approximately spherical in shape. Other phases, including shapes such as ellipsoids, cylinders, and bilayers, are also possible. The shape and size of a micelle are a function of the molecular geometry of its surfactant molecules and solution conditions such as surfactant concentration, temperature, pH, and ionic strength. The process of forming micelles is known as micellisation and forms part of the phase behaviour of many lipids according to their polymorphism.

hey mate here is your answer
Micelles
Introduction:
A micelle is formed when a variety of molecules including soaps and detergents are added to water. The molecule may be a fatty acid, a salt of a fatty acid (soap), phospholipids, or other similar molecules.
The molecule must have a strongly polar "head" and a non-polar hydrocarbon chain "tail". When this type of molecule is added to water, the non-polar tails of the molecules clump into the center of a ball like structure, called a micelle, because they are hydrophobic or "water hating". The polar head of the molecule presents itself for interaction with the water molecules on the outside of the micelle.
Structure of a Micelle:
The theoretical model shows 54 molecules of dodecylphosphocholine (DPC) and about 1200 H2O molecules. Each lipid has a polar head group (phosphocholine) and a hydrophobic tail (dodecyl = C12).
The graphic on the left represents a cross section of a micelle.
The gray spheres on the interior represent the long hydrocarbon chains of the dodecyl groups which are massed together because they are non-polar.
The polar head groups of the phosphate are shown as red and orange spheres. The amine nitrogen is shown in blue surrounded by the gray methyl groups.
The water molecules are represented as red and white spheres surrounding the outside of the micelle and penetrates all of the spaces in the head group region.
the hydrophobic tails are shown Spacefill. H2O is excluded from this entire interior volume. The hydrocarbon chains vary in their individual conformations (e.g. trans/gauche configuration at each carbon-carbon bond), but adapt so as to fill all of the interior space.
hope it will help you
