You take 50 times .082 which is 8.2% in decimal form to get 4.1
I believe the answer is (a+c, b) but I'd double check to make sure.
Answer:
2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 2, 4 ] , then
f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12
f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0
Then
average rate of change =
=
= 2
Area of circle = π · r²
9 π = π · r²
9 = r²
3 = r
Volume of sphere = (4/3)π · r³
= (4/3)π · (3)³
= 4π · 3²
= 4π · 9
= 36π
Answer: the volume of the sphere is 36π
