Answer:
3π square units.
Step-by-step explanation:
We can use the disk method.
Since we are revolving around AB, we have a vertical axis of revolution.
So, our representative rectangle will be horizontal.
R₁ is bounded by y = 9x.
So, x = y/9.
Our radius since our axis is AB will be 1 - x or 1 - y/9.
And we are integrating from y = 0 to y = 9.
By the disk method (for a vertical axis of revolution):
So:
Simplify:
Integrate:
Evaluate (I ignored the 0):
The volume of the solid is 3π square units.
Note:
You can do this without calculus. Notice that R₁ revolved around AB is simply a right cone with radius 1 and height 9. Then by the volume for a cone formula:
We acquire the exact same answer.

Answer:
Mr. Herrera will hike 78 miles on 6th day.
Step-by-step explanation:
Given:
Number of miles Mr. Herrera will hike in 9 days = 117 miles
Total Number of days =9 days
Let us first find the number of miles he will hike in 1 day
By Using Unitary method we get,
Number of miles Mr. Herrera will hike in 1 days=
We need to find miles hiked in 6th day.
Number of miles Mr. Herrera will hike on 6th day= Number of miles Mr. Herrera will hike in 1 days Number of days =
