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 area of a circle with a radius of 2m is: 12.566 m2
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).

It would be 18 square meters. You find that out by multiplying 9m x 2m. You're welcome :)
No, no it can't. Circumference = 2r*pi Area = pi*r2 For the area to equal the circumference pi*r2 = pi*2r so divide both sides by pi r2 = 2r so divide both sides by r r = 2 Note that circumference is in units and area is in units squared i.e. radius = 2m, area = 12.56637m2 Ciercumference = 12.56637 m
The area of a circle with a radius of 2m is: 12.566 m2
3.1416 square m
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
12m2
It would be 18 square meters. You find that out by multiplying 9m x 2m. You're welcome :)
