Six square roots of two

(square root of  72)  =  square root of (36  times  2)

That's the same as  (square root of  36)  times  (square root of  2).

But the square root of  36  is  6 .

So the square root of  72  is    (6)  times  (square root of  2) .

A cylinder has a volume of 486 pi ft^3. if the height is 6ft what is the diameter
rusak2 [61]

Answer:

18

Step-by-step explanation:

Alright so here you have to work backwards. the volume of a cylinder is pi*r^2*h.

Your equation: 486 pi = pi*r^2*6

You know the height is 6 feet, so you can get rid of the 6 feet hanging off of your equation by dividing both sides by 6:

81 pi = pi*r^2

Now you notice that both sides have pi. You can eliminate it by dividing both sides by pi:

81 = r^2

To isolate the r, radius, you have to take the square root of both sides, since a square root is the inverse operation of squaring. You get:

9 = r

Now that you have the radius, you can find the diameter by multiplying the radius by 2, because a diameter = 2 * the radius:

18 = d

Hope this helps!
