Nasim fills a measuring jug with 310 cm of water. She pours the water into a cylin- drical vase with radius 4 cm. Find the height of water in cm.

The height of water of the jug in cm is; 6.2 cm

We are given radius(r) = 4cm

V = πr²h

Thus;

310 = π × 4² × h

h = 310/(16π)

h = 6.167 cm

Approximating, we have; h = 6.2 cm

The height of water in the cylindrical vase is 6.2 cm.

Step-by-step explanation:

Volume of water in the measuring jug = 310 .

The radius of the cylindrical vase = 4 cm

volume of cylinder = h

But,

volume of water in the jug = volume of water in the vase = 310

So that,

310 = x x h

     = x 16 x h

310 x 7 = 22 x 16 h

2170 = 352h

h =

  = 6.163

h = 6.2 cm

The height of water in the cylindrical vase is 6.2 cm.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
