F(2)=8 and f(5v)=25v^2+15v-2
METHOD 1
f(3) = 20
f(4) = 30
f(5) = 42
f(6) = 56
rate of change
f(4)-f(3)=10
f(5)-f(4)=12
f(6)-f(5)=14
then the average of change is 10+12+14 /3 = 12
METHOD 2 --- faster
rate of change = f(6)-f(3) / 6-3
= (36+18+2)-(9+9+2) / 3
= 36/3 = 12
Whole formula 2*pi*radius^2 + 2*pi*radius*height:
157+942= 1099
SA= 1099
There are 6/10 left over. 6/10 reduces to 3/5.
