X^2 = 9x + 6
x^2 - 9x - 6 = 0
use quadratic formula : (-b (+-) sqrt b^2 - 4ac) / (2a)
a = 1, b = -9, c = -6
now we sub
x = (-(-9) (+-) sqrt -9^2 - 4(1)(-6)) / 2(1)
x = 9 (+-) sqrt 81 + 24)/2
x = 9 (+-) sqrt 105) / 2
x = 9/2 + 1/2 sqrt 105 or x = 9/2 - 1/2 sqrt 105
x = 4
First you combine like terms:
8 + 4x = 24
Then solve:
4x = 24 - 8
4x = 16
x = 16/4
x = 4
the volume of the cylinder is 572.27 cm³
Explanation:
Given:
radius of the cylinder = 4.5cm
height = 9cm
To get the volume of the cylinder, we will use the formula:
To the nearest hundredth, the volume of the cylinder is 572.27 cm³
