Answer:

No

Step-by-step explanation:

When you square a number, you chose a number and multiplying itself. If you did the square root of 25, you would get 5. However if you divided 25 by 2, you would get 12.5 which is NOT the square root.

Answer:

No,  that is not what the definition of square root is.

Step-by-step explanation:

what \sqrt{25} means is that  \sqrt{25} = x  where  x * x = 25

It means find a number x such that  x times x equals 25.

In this case we know 5*5 = 25,   so we say 5 = \sqrt{25}

A height of 12 and a volume of 1.356.48 what is the radius of the cylinder?
alexgriva [62]

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)
