Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2
r
where C is the circumference and r its radius.
r = 
= 
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ = 
Tan 55 = 
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.
In order to determine this, we will first need some conversions. We will need to convert metric tons and grams into one another and also cubic centimeters to cubic meters into one another.
1 metric ton = 1000 kg
1 kg = 1000 grams
1 metric ton = 10⁶ grams
So 10⁶ grams / metric ton
1 meter = 100 cm
1 m³ = (100)³ cm³
1 m³ = 10⁶ cm³
So 10⁶ cm⁶ / m³
Now, we manipulate the given value:
(19.3 grams / cm³) * (1 metric ton / 10⁶ grams) * (10⁶ cm³ / m³)
= 19.3 metric tons / m³
The density of gold is 19.3 metric tons meter meter cubed.
