Question

The figure shows the layout of a symmetrical pool in a water park. What is the area of this pool rounded to the tens place? Use the value "pie"= 3.14.

Answer 1

Area of pool = 2 x area of sector + 2 x area of triangle

Area of sector =

(2.21/2π) * π * (30)² = 994.5 ft^2

Area of triangle =

1/2 bh = 1/2 x 20 x 25 = 250 ft^2

Area of pool = 2(994.5 + 250)

= 2489 ≈ 2490 ft^2
