The image shows a circular ring with a shaded region between two concentric circles. The outer circle has a radius of 43 meters, and the width of the ring is 1.5 meters.

Question

To find the area of the shaded region (the annulus), we need to calculate the area of the larger circle with radius 43 meters and subtract from it the area of the smaller circle. The radius of the smaller circle would be the radius of the larger circle minus the width of the ring.
whats the answer

Answer 1

The radius of the smaller circle is 43 - 1.5 = 41.5 meters.

The area of the larger circle is π * (43)^2 = 5808.51 square meters.
The area of the smaller circle is π * (41.5)^2 = 5403.88 square meters.

Therefore, the area of the shaded region (annulus) is 5808.51 - 5403.88 = 404.63 square meters.
