If the diameter is 2m, then the area is approx 6.28 square metres.
The circumference of a 2m diameter circle is: 6.283 meters.
The circumference of a circle with diameter 2m is about 6.28m
π square meters ~= 3.14m2. Area circle = πr2 radius = diameter/2 => radius = 2m/2 = 1m => area = π x 12 = π sq m

The area of a circle with a radius of 2m is: 12.566 m2
Since you didn't state If the 2m was a diameter or radius, it will have to be calculated as If it were both: Diameter: Pi x D = Area of Circle 3.14 x 2m = 6.28 m² Radius: Pi x R² = Area of Circle 3.14 x 2m² = 3.14 x 4 = 12.56 m²
If the diameter is 2m, then the area is approx 6.28 square metres.
The circumference of a 2m diameter circle is: 6.283 meters.
The circumference of a circle with diameter 2m is about 6.28m
π square meters ~= 3.14m2. Area circle = πr2 radius = diameter/2 => radius = 2m/2 = 1m => area = π x 12 = π sq m
It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).

The area is four times as large if the diameter doubles.The area of a circle is A = (pi)r2 or (pi)(diameter/2)2Since d is squared, it increases the area by the square of 2 if the diameter is doubled.Try calculating the area for a diameter of 2m, 4m and 8m to prove this.
The surface area of a cylinder with a radius 2m and 9m height is 138.23m2
When you say "2m by 3m," you are referring to the dimensions of a rectangle. The "2m" represents the length of the rectangle, and the "3m" represents the width. To find the area of the rectangle, you would multiply the length by the width. In this case, the area would be 2m x 3m = 6 square meters.
