Question

A pool is comprised of a rectangle with 2 semicircles on the ends.

The local public pool is a rectangle with two semicircles.


The area of the rectangle is .



Using 3.14 for π and rounding to the nearest meter, the area of each half circle is m2.



The area of the surface of the pool is m2.

Answer 1

Explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

Length = 100 m

Width = 52 m

Area of rectangle = 100 × 52 = 5200 m²

A semicircle is half of a circle

The formula for determining the area of a semicircle is

Area = 1/2 × πr²

Diameter = 52 m

Radius = diameter/2 = 52/2

Radius = 26 m

The area of each semicircle is

1/2 × 3.14 × 26² = 1061.32 m²

The area of the surface of the pool is

1061.32 + 1061.32 + 5200 = 7322.64 m²

Answer 2

5200

1061

7322
