The formula for the area of a circle is A = pi x r2 where r is the radius. If the diameter of the circle is 10 meters, then the radius is half that amount or 5 meters. Plug that value into the formula for r, using 3.14 as an approximation for pi. The area is 3.14 x 52 or about 78.5.
a circle having a diameter of 1.4732 meters has an area of about 1.7 square meters.
A circle with an area of 2.0 square meters has a diameter of : 1.596 meters.
A circle with a radius of 30 meters has an area of 2827.43 square meters.
A circle with a diameter of 220 meters has an area of 38,000 square meters.
Area = pi*72 = 153.938 square meters
The area of a circle with 6 meters diameter is 9xpi square meters. The area of circles with 4 meters diameter and 2 meters diameter are 4xpi and 1xpi square meters respectively. The combined area is 5xpi square meters. Thus the area 6 diameter circle exceeds the combined area by (9-5)xpi= 4xpi square meters. Substituting the value of pi as 3. 14, the exceeding area is 12. 56 square meters.
