Adding up all of the values in the histogram, there were 20 cars sold in total. Of those, 5 were under 20 years old and 3 were more over 40. That means that 8/20 of the cars fit the bill. Multiplying the numerator and denominator by 5, we find that 8/20 = 40/100, or 40%.
8 friends, 16 slices. Easy math 16÷8. Everyone gets 2 slices.
Volume= π*2.5²*7 + 2/3 * π * 2.5³ = 170 in^3
Let
a--------> original side length side of a cube
we know that
[volume of a original cube]=a³
<span>If the side lengths are decreased to 50% of their original size
then
[volume of a new cube]=(a/2)</span>³----> a³/8
the answer is
the volume of the new cube is a³/8
