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 = 3.14.

Answer 1

where the figure..????

Answer 2

Answer :-

Area of pool = Area of circular sector + Area of traingle

Area of circular sector = 2 x pi x 30^2 x (2 x 21 / 2 pi) = 1989 ft^2

Area of triangle using Heron's formula

s = (30 + 30 + 20 ) /2      

Area of triangle = 2 x Sqr Root ( 40 x ( 40 - 30) x (40 -30) x (40 - 10) ) = 400 √2 ft²

So total area of pool = 1968 + 400 √2 ft²
