Answer:
11
Step-by-step explanation:
f(x) = 3x + 2
Let x = 3
f(3) = 3*3 +2
f(3) = 9+2
= 11
we can divide this shape into two parts
(1) Hemisphere:
we can see that
radius is 8
now, we can use formula for volume
(2) Cylinder:
radius is 8
height is 7
we can use formula
now, we can add them to find total volume
..............Answer
42.7/7= 6.1
36.48/6=6.08
7.29/9=0.81
-1
When the graph has an x value of 3, the corresponding y is -1
