Answer:
39 pi cubic inches
Step-by-step explanation:
The volume of a cone is (1/3)(area of the base)(height).
Find the area of the circular base. The circumference of a circle is 
, so
Now that you know the radius of the circular base, you can find its area:
The height of the cone is 13. Time to use the volume formula.
Let's say that B makes $100.
Then A makes $75.
So, your question then becomes 100 is what percent of 75?
This can be solved by setting up the proportion 100 / 75 = x / 100
75x = 10000
x = 133.3
So, B's income is 33.3% more than A's income.
Please use " i " to denote "interest."
the formula for simple interest is i = p r t.
Here, i = $160.67 = $2000 (r) (8/12)
Solving for the interest rate, r = ($169.67)(12/8)/ $2000 = 0.127, or 12.7%
