Yes it is an irrational number
Hello!
The area of a cylinder formula- Area = Pi * radius squared * height
<span>In this case we are looking for height (altitude) </span>
<span>plug in our known values </span>
<span>500 = area </span>
<span>4 = radius </span>
<span>Pi ~ 3.141592654 </span>
<span>to find height... </span>
<span>500 = 3.141592654 * (4)^2 * height </span>
<span>500 = 3.14 * 16 * height </span>
<span>500 = 50.26 * height </span>
<span>divide both sides by 50.26.. </span>
<span>9.947 = height
</span>
<span>9.95 is the Correct Answer ( letter C)
</span>
Hope this Helps! Have A Wonderful Day! :)
32.75 + 39.88 = 72.63
72.63 x 114% = 72.63 x 1.14 = $82.7982 or $82.80 to the nearest cent.
114% is all of the cost of the meal plus 14 % extra for the tip. See how muliplying by 1.14 includes the $72.63 (this saves the step of adding it on at the end if you were only to find 14% of $72.63)
