π square meters ~= 3.14m2. Area circle = πr2 radius = diameter/2 => radius = 2m/2 = 1m => area = π x 12 = π sq m
Using 3.14 as Pi the area of circle is: 12.56
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
Area of a circle = pi R2If 'R' (the radius) is 1 meter, thenArea = pi (1)2 = pi = 3.142 square meters (rounded)
