75.4 or 75.398. So we can plug in the formula pi*r^2*h. R being radius and h being height. So then we can put and get pi*2^2*6 = pi*4*6 = pi*24 = 75.398 = 75.40.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
