Speed is the derivative of distance, x(t), with respect to time.
speed = dx/dt = 4t³ - 30t² + 58t - 36
The time at which the speed is greatest is the derivative of the speed equated to zero.
ds/dt = 12t² - 60t + 58 = 0
The value of t from the equation are 3.69 and 1.31 seconds.

(2 x p) + (3x r ) = T that would be the equation
For this case we have that by definition, the volume of a cone is given by:
Where:
r: It is the radius of the cone
h: It is the height of the cone
According to the statement data we have:
So, the volume is:
Thus, the volume of the cone is:
