Think: You're treating the numerator and the denom. in precisely the same way. In doing so you are NOT changing the value of the fraction, only the appearance.
Example: start with 2/3. Mult num. and den. both by 7: 14/21.
2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.
The radius of your cone is half of 18 units = 9 units.
The volume of any cone is <span><span>V = (1/3) · (pi) · (radius)² · (height) </span>
</span>
-- Take that formula for the volume of any cone.
-- Write '8' in place of 'height'.
-- Write '9' in place of 'radius'.
-- Write '3.142' in place of 'pi'.
-- Complete the arithmetic.
-- Bada-bing, you've got the volume.
A. -2 6/7, -3/2, 2.25, 2 1/3
B. 10:00 AM and 4:00 PM
C. The biggest change was 2.25 to -2 6/7, or 4:00 AM to 10:00 AM
D. I'm not sure what part C is referring to so I can't help with that one.
E. I believe it will decrease since it tends to decrease as the day goes on and then increase once again. (that seems to be the pattern, at least)
