By definition, the volume of a cone is given by:
Where,
r: radius of the circular base
h: height of the cone
Let's define a variable:
x: diameter of the base
We have then that the radio is:
The height is:
Substituting values:
Rewriting:
Answer:
An expression that represents the volume of the cone, in cubic units is:
Answer:
i think 9900
Step-by-step explanation:
225x20 = 4500
180x30 = 5400
5400+4500 = 9900
the dolphin is 8 ft from its starting point (option A)
Explanation:
The path model:
Considering the water's surface as the starting point, the value of y = 0
And x = distance from its starting point
We substitute for y in the model:
Then we find the values of x:
From our result, the dolphin is 8 ft from its starting point (option A)
