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
The answer will depend on which of the two measures is the height of the cylinder and which is the radius.
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).
2m = 26m = 26/2m = 13
The area of a circle with a radius of 2m is: 12.566 m2
The surface area of a cylinder with a radius 2m and 9m height is 138.23m2
Assuming that raduis is mean to be radius, the answer depends on what characteristic of what shape the 2m measures.

What is the amount of water can fill in this tank 2m x 2m 2m.
Circumference = Pi x 2r = Pi x 2m = 6.283 metres (to nearest 3rd decimal).
30 percent of 2m = 0.6m30% of 2m= 30% * 2m= 30%/100% * 2m= 6/10m or 0.6m
2m is 200cm..
π square meters ~= 3.14m2. Area circle = πr2 radius = diameter/2 => radius = 2m/2 = 1m => area = π x 12 = π sq m
