The volume of a cone is given by the formula
... V = (1/3)π·r²·h
You are given
... V = 35 in³; r = 2.4 in; π = 3.14.
Fill in the given information and solve for the remaining variable.
... 35 in³ = 3.14·(2.4 in)²·h
... (35 in³)/(18.0864 in²) = h . . . . . . . divide by the coefficient of h
... 1.94 in = h
The height of the cone is 1.94 inches.
