standard form:

We will complete x , y and z square

make all x , y and z terms together

$x^2-2x+y^2-4y-z+5=0$

$x^2-2x+y^2-4y-z=-5$

$x^2-2*1*x+y^2-2*2*y-z=-5$

$x^2-2*1*x+1^2+y^2-2*2*y+2^2-z=-5+1^2+2^2$

$(x-1)^2+(y-2)^2-z=0$

$z=(x-1)^2+(y-2)^2$

Can someone help me with this?

uysha [10]

Step-by-step explanation:

Volume of a cylinder : πr^2*height.

Volume : 150cm^3

height : 7.2m

π =3.14

150 = 3.14*r*r*7.2

150=22.608*r*r

r^2= 150/22.608

=150/23cm^2

r=√6.5

r=2.569cm

r=2.6cm
