The volume of a right circular cone is calculated through the equation,
V = πr²h
where V is volume, r is radius of the base, and h is height. Given that height is 3 ft, this can be simplied into,
V = 3πr²
The rate of change with respect to r is,
dV/dr = 6πr
Substituting the DALE,
dV/dr = (6)π(2 m)² = 24π
Answer: 24π.
The formula for this problem is A=P(1+(r/n))^nt.
A is what you're trying to find. P=400 r=0.06 t=3 n=1, since it's compounded once per year.
Now plug in those values to get A=400(1+(0.06/1))^1*3
I get an answer of $476.41
If you multiply 208.15 * .05 you get 10.4075 so the tax would be 10.41
The answer is -6 -/+ 4i. Hope this helps.
3600 if you multiply 40 to 80<span />
