Answer:

r = 4, s = 3, t = 5

Step-by-step explanation:

<u>Solving quadratic equation:</u>

5x² - 8x + 5 = 0
x = (-b ± √b²-4ac)/2a
x = (8 ± √8²-4*5*5)/2*5
x = (8 ± √64-100)/10
x = (8 ±√-36)/10
x = (8 ± 6i)/10
x = (4 ± 3i)/5

x = (r ± si)/t

r = 4, s = 3, t = 5

A cylinder has a circular base with a diameter of 12 ft the height of the cylinder is 4 feet what is the volume of the cylinder

Murrr4er [49]

Answer:

$452\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$r=12/2=6\ ft$ ----> the radius is half the diameter

$h=4\ ft$

substitute the values

$V=(3.14)(6^{2})(4)=452\ ft^{3}$
