Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 2, 4 ], thus
f(b) = f(4) = 16 ← corresponding value of y from table
f(a) = f(2) = 4 ← corresponding value of y from table , thus
average rate of change = =
= 6 → A
Answer:
Volume of the machine part = 114π inches³
Step-by-step explanation:
Volume of the machine part = Volume of cylinder + Volume of hemisphere
Volume of cylinder =
Where r = radius of the cylinder
h = height of the cylinder
Volume of the cylinder =
= 108π inches³
Volume of the hemisphere =
=
= 6π inches³
Total area of the machine part = 108π + 6π
= 114π inches³
