$V= \frac{4}{3} \pi r^{3} or V=4.1888 r^{3}$

r=4 $r^{3}$ =64*4.1888=268.083

V = 268.083 $mm^{3}$ so go with A.

The volume of the cell phone is 75 cubic centimeters. Write and solve an equation to find the height of the cell phone. Round yo

prohojiy [21]

Answer:

Equation: $Height = \frac{75}{Area}$

Step-by-step explanation:

<em>The question is incomplete as the dimension of the phone was not given.</em>

<em>However, the following explanation will guide you</em>

Given

$Volume = 75\ in^3$

Required

Determine the Height

Volume is calculated as thus;

$Volume = Area * Height$

Substitute 75 for Volume

$75= Area * Height$

Divide through by Area

$Height = \frac{75}{Area}$

<em>The above represent the equation to solve for Height</em>

<em>To solve for height, we need the dimension of the phone or the area.</em>

Take for instance; the length and width of the phone is 5 by 5 inches;

The height would be:

$Height = \frac{75}{5 * 5}$

$Height = \frac{75}{25}$

$Height = 3\ inches$

2). Bill has twice as many candies as Fred. Tim has 3 fewer than 3 times as many candles as Fred.

sasho [114]

Step-by-step explanation:

<h2>Answer:-</h2>

$\tt{Let \ the \ candies \ taken \ by \ Fred \ be \ x.}$

Now, let's Solve!

So, according to Question,

Bill = 2x

Tim = 3x-3

Total Candies = 177.

$\bf{x+2x+3x-3=177}$

Totalling x,

$\bf{6x-3=177}$

$\bf{6x=177+3}$

$\bf{6x = 180}$

$\boxed{\sf{x = 30}}$

So, Fred has 30 candies.

Bill's Candies = 2×30 = 60 Candies

Tim's Candies = 3×30-3 = 90-3 = 87 Candies.

Hope it helps :)
