A special truck cleans the surface of the ice rink shown below. The figure is composed of a square and two semicircles. If the truck cleans the entire surface, how many square meters of ice will the truck clean? Use 3.14 for pi. Rou d your answer to the nearest tenth

1,660.5 m²

Step-by-step explanation:

The question is as shown at the attached figure.

At first we should know that:

The area of square of side length l = l²

The area of circle of radius r = πr²

As shown, The figure is composed of a square and two semicircles.

The square has a side length = 30.5 m

Each semicircle has a diameter 30.5 m

So, the radius = half of the diameter = 0.5 * 30.5 = 15.25 m

So, the area of the square = 30.5² = 930.25 m²

The area of one semicircle = 0.5 πr² = 0.5 * 3.14 * 15.25² = 365.123 m²

∴ Total area = 930.25 + 2 * 365.123 = 1,660.5 m² (to the nearest tenth)

So, the truck will clean 1,660.5 m² of ice.
