Sometimes used caves as shelters, they often built shelters out of tree branches. With their chopping tools they hacked branches from young trees, probably trimming off the twigs, and then they poked the branches into the ground in rough circle, holding them in place by piling rocks against them. The tops of the branches were probably bent and twisted together so that the finished hut was more or less tent shaped. The remains of such a hut has been found holes made by branches that were pushed into the ground, rocks that were once piled against these branches, and a circle of stones in the center where a fire was kept burning. but although these people could build crude huts, they did not live together in villages.

The circle must have a radius. If you do not know it then you find out the area using the diameter, (this is the length of two points directly across from each other on the circle.The equation for the area of a circle when using the diameter =π × (d/2)²By the way, π is approximately = 3.14159265. or 22/7A circle with no radius has no area and is sometimes considered by certain branches of geometry and topology as a point.
I beileve (Looking in my Hole's anatomy & physiology text) that the anterior cerebral branches off the middle cerebral, which branches from the posterior communicating artery. Or it circles around to the anterior communicating artery. They all form the cerebral arterial circle.
Homo habilis was known to live in simple shelters such as natural rock overhangs or caves. They likely used sticks, leaves, and other available materials to create additional protection from the elements. Their shelters were not as elaborate as those constructed by later hominids.
