You estimate that approximately 10 adults lived in pit house with a diameter of 8 m. using this estimate, how many adults might have lived in a pit house with a diameter of 12 m? does anybody have any idea how to do this one? i am trying to get the answer 23 but idk how to do it. i have also given some other information which 1 adult takes 4 of area. but it's kind of non-beneficial because the question is an estimation. and that's all. asap.

If we assume the pit house is a perfect circle, its total area would be

A = pi*(r**2) = pi*(4**2) = 50,265 m2

If we divide the area by the number of adults, we get that each person used

an area of approximately 50,265/10 = 5,02 m2 of area per person

With a Diameter of 12m, the new area would be A = pi*((12/2)**2) = 113,1 m2

If we use the previous estimate of area occupied by a single person, we get that  113,1 / 5,02 = 22,529.

So, an estimate of 22 people would be living now in the pit house.

(Note, that if we use 4m2 as the space it takes to house 1 person inside the house, we would have 113,1/4 = 28,275.

So 28 people would live there)

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept
