The actual area is 454.1 ft.
You can use a ratio to find the actual diameter:
18cm/3cm = x/4ft.
x = 24 ft.
Then find the area using A=pi*r^2
A=pi*144
A=452.4 ft.
The problem given above is simply a conversion problem. <span>We
are asked to convert from units of acres to units hectares. To do
this, we need a conversion factor which would relate the different units
involved. We either multiply or divide this certain value to the original
measurement depending on what is asked. For this case, we use the given values to determine the relation. We do as follows:
1 hectare = 100 m x 100 m = 10000 m^2
1 hectare = 10000 m^2 ( 1 ft / 0.3048 m )^2 = 107639.10 ft^2
107639.10 ft^2 ( 1 acre / 43600 ft^2 ) = 2.47 acre
Thus, 1 hectare = 2.47 acres
12.0 acres ( 1 hectare / 2.47 acres ) = 4.86 hectares
