The volume of a cylinder is 770 cm. It's height is 5 cm. Find its approximate radius.

Alinara [238K]

Hey there,

The equation for the volume of a cylinder is V = πr²h.

The first step into finding the radius is to plug in what you already know into the equation:

770 = πr²5

We divide both sides by 5:

154 = πr²

Now we divide both sides by π:

49.0197224723 = r²

Finally we just do the square root of 49.0197224723:

7.0014086063 = r

The radius therefore would be about 7cm.

Hope I helped,

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. A rocket is launched from atop a

umka2103 [35]

When it hits the ground, then h=0
find the xintercept or in this case the tintercepts
c=76
v=135

h=-16t^2+135t+76
use quadratic formula

ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

a=-16
b=135
c=76

x= $\frac{-135+/- \sqrt{135^2-4(-16)(76)} }{2(-16)}$
x= $\frac{-135+/- \sqrt{18225+4864} }{-32}$
x= $\frac{-135+/- \sqrt{23089} }{-32}$
aprox
x=-0.5297 or 8.967
exclude the negative root since you can't have negative time

means that it takes 8.97 seconds to hit the ground
