Step-by-step explanation:
Firstly convert the diameter into cm
t480812.5cm³hus 3.5×100=350cm
Volume=


=480812.5cm³
So.. 2.86 - 2.79 is the amount in decrease or 0.07
so.. if we take 2.86 as the 100%, how much is 0.07 of that in percentage?
well

solve for "x"
Using the midpoint formula we get:
(x,y)=(0+5/2, 0+12/2) or (5/2, 6) as the midpoint.
Common ratio, r is found by dividing the next term by the previous term
r =

= -3
you can see this value is true for any consecutive pairs of terms
also, multiply by -3 to get the next term
