Answer 3

Calculating the Area of a Circle

To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle.

Let's calculate the areas of circles with radii of 1 and 2 meters.

For a circle with a radius of 1 meter: - Radius (r) = 1 meter - Area (A) = π(1^2) = π square meters.

For a circle with a radius of 2 meters: - Radius (r) = 2 meters - Area (A) = π(2^2) = 4π square meters.

Therefore, the area of a circle with a radius of 1 meter is π square meters, and the area of a circle with a radius of 2 meters is 4π square meters.
