Answer:
Volume = h * w * l (height, width, length)
Volume = 4* 6 * 3
Volume = 72 cube meters
Surface area is finding the are of every 2D plane on the solid.
2(w * h) + 2(l*h) + 2(w * l)
Surface are = 108 square meters

Answer:
dx/dt = 0,029 ft
Step-by-step explanation:
Let call "x " diameter of the base of the cone then h (height ) is equal to x
V = ( 1/3)* A(b) *h
A(b) = π*(x/2)²
Then
Volume of the cone is
V = ( 1/3)*π*(x/2)²*x
V = ( 1/12)*π*x³
Then:
dV/dt = ( 1/12)*π* 3*x²*dx/dt ⇒ dV/dt = ( 1/4)*π*x²*dx/dt
dV/dt = (1/4)*π*(21)²*dx/dt
As dV/dt = 10 ft³
10*4 = 441*π* dx/dt ⇒ dx/dt = 40/ 1384,74
dx/dt = 0,029 ft
