Best Answer

Area of a circle = pi R2

If 'R' (the radius) is 1 meter, then

Area = pi (1)2 = pi = 3.142 square meters (rounded)

A circle with a radius of 10 meters has an area of 314 square meters.

Area: pi*1.52 = 7.069 square meters rounded to 3 decimal places

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 55 meters, the radius, which is half the diameter, will be 25 meters.So to solve for the area (A) of this circle:A = pi x r2 = 3.1416 x 25m x 25m = 1963.5m2 = 1963.5 square meters.

If the radius of a circle is 80 inches, then the area of the circle is 139.6263 square feet. (rounded)

A circle with a diameter of 220 meters has an area of 38,000 square meters.

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.

Area: pi*1.52 = 7.069 square meters rounded to 3 decimal places

The area of a circle is πr2 If we use 3.1416 as the value of π, and insert the value of 30 for the radius we get 3.1416 x 900 which gives a result of 2827.44 square metres.

Area = pi*r2 = 467.6 sq metres, approx.
