Answer:
Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi
Step-by-step explanation:
The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
5x15, 3x25 because 30+45=75 and both 5x15 and 3x25 equal 75

Just subtract 622 feet from 486 feet to get the change in elevation. The result will be negative because your friend's house is at a lower elevation than yours.
Now find the mean change in elevation per mile by dividing (486 ft - 622 ft) by 4 miles:
-136 ft
----------- = -34 ft/mile
4 mi
