NO, because it already is
About 32.5 square meters. (32.516064 square meters)
It doesn't need to be rounded. 2.1 km is the same as 2,100 meters. That's already rounded to the nearest meter, the nearest 10 meters, and the nearest 100 meters.
10 square meters rounds to 107.64 square feet.

-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
1598 to 1629
4.0386*3.8862 = 15.69480732 square metres or 16 to the nearest square metre.
1.267 meters to the nearest 10 meters is zero meters.
Presumably you mean the area of a circle? Area of a circle = pi*radius2 Area = pi*3.82 = 45.36459792 Area = 45 square meters to the nearest square meter.
A square with an area of 32 meters would have a side of 5.657, as the square root of 32 is 5.657. using this as the length of one side you simply multiply it by 4.5.657X4= 22.628 or rounded to the nearest tenth 22.6
