The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that

[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in

the answer is
8 in

In a sale, all normal prices are reduced by 15%

sladkih [1.3K]

Answer:

The normal price of mixer is $150.

Step-by-step explanation:

Given that:

Normal prices are reduced by 15% in sale.

The normal price of mixer is reduced by $22.50

It means that it is the amount of discount.

Let,

x be the normal price of the mixer.

15% of x = 22.50

$\frac{15}{100}x=22.50\\0.15x=22.50$

Dividing both sides by 0.15

$\frac{0.15x}{0.15}=\frac{22.50}{0.15}\\x=150$

Hence,

The normal price of mixer is $150.

Factor 2x^2-128 completely

Alina [70]

2x² - 128

2(x² - 64), but (x² - 64) = x² - 8² (difference of 2 squares),[a²-b²=(a-b)(a+b)]

2(x² - 64) = 2(x² - 8²) = 2(x-8)(x+8)
