the volume of a sphere whose diameter is 18 centimeters is ? cubic centimeters. If its diameter were reduced by half its volume

Ghella [55]

A) The formula for the volume of a sphere in terms of its radius (half the diameter) is
$V= \frac{4}{3}\pi r^{3}$
For your 18 cm sphere, the volume is
$V= \frac{4}{3}\pi(9 cm)^{3} = 972\pi \cdot cm^{3} \approx 3054 cm^{3}$

B) If the diameter were reduced by half, the volume would be $(\frac{1}{2})^{3}=\frac{1}{8}$ of the original volume.

In the table adam recorded the miles he travled each day while traveling from Florida to California. Calculate the average rate

blagie [28]

Hi!

<em>To calculate the rate of change between days 4 and 6, we simply take those points, (4, 1503) and (6, 2196) and use the equation in the picture below:</em>

<em />

Now, when we plug it in the equation, it looks like this:

$\frac{2196-1503}{6-4} = \frac{693}{2} = 346.5$

Therefore, your answer is 346.5 or, rounded, 347.

<em><u>Meaning, your answer is C</u></em>
