Answer:

Step-by-step explanation:

area of a cylinder = (area of a circle) times the (height)

area of a cylinder = π radius² × height

radius = 57 cm height = 40 cm

area of a cylinder = π 57² cm² × 40 cm

= π (57² × 40) cm³

= π ( 57 × 57 × 40) cm³ 57x57 = 399 + 2850 = 3249

= π (3249 × 40) cm³

= 129969π cm³ π = 3.14

= 129969 × 3.14 cm³

= 408,074.4 cm³ < ----------------- Final Answer

Answer:

V(w) = 6*w³ [cubic units]

Step-by-step explanation:

h height of the rectangular prism

L the length of the base

w the width of the base

Then the volume of the prism is area of the base times heigth therefore

V(p) = L*w*h [cubic units] (1)

Now the length of the base L = 2*w

And the height of the prism is h = 3*w

If we plugging these values in equation (1) we get olume of a prism as function of w then

V(w) = 2*w* w * 3*w

V(w) = 6*w³ [cubic units]
