16 square meters, to 2 significant digits. The area of a circle is calculated as the value pi (3.1416...) times the square of the radius of that circle. In this case, where a circle has a diameter of 4.2 meters, the radius, which is half the diameter, will be 2.1 meters. So to solve for the area (A) of this circle: A = pi x r2 = 3.1416 x 2.1m x 2.1m = 15.954456m2 = 16 square meters.

A circle with a diameter of 18 meters has an area of 254 square meters.

A 7-meter diameter circle has an area of 38.5 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.

A circle's diameter is twice its radius.

The diameter of a circle is twice length of a radius, because it is basically two radii (plural of radius) joined together so they form a continuous line across the circle. If you multiply the length of the radius, 40 meters, by 2, then you get the length of the diameter, 80 meters.
