a height of 12 and a volume of 1.356.48 what is the radius of the cylinder?

Respuesta :

Answer:

11.99 ft

Step-by-step explanation:

The formula for the volume of a cyl. of radius r and height h is V = πr²h.

Solving this immediately for h yields:

        V

h = ----------

        πr²

Inserting the known quantities results in:

        V           1356.48 ft³

h = ---------- = ----------------------      Note that r = (1/2)d, so r = (1/2)(12 ft) = 6 ft

        πr²         3.14159 (6 ft)²

  =   11.994 ft

The height of the cyl. is 11.99 ft (to the nearest hundredth foot)
