What do ya need help with?
Step-by-step explanation:
It should be a cylinder generated by the rotation. Take a piece of paper or book and rotate it with one edge as the center, and visualize what shape it makes. Doing something like this will be the best way to understand what shape it forms.
In form:
378 = 111-w
Solving for w:
378-111 = -w
-w = 267
w = -267
Answer:

Step-by-step explanation:
You want to calculate the interest on $40000 at 5.7% interest per year after 17 years.
The formula we'll use for this is the simple interest formula, or:

Where:
- P is principal amount, $40,000
- r is the interest rate, 5.7% per year, or in decimal form,

- t is the time involved, 17 years
To find the simple interest we multiply
to get
The interest rate is $38,760
Usually now, the interest is added onto the principal to figure some new amount after 17 years.
or 40000.00 + 38760.00 = 78760.00
=$78,760
