Answer:
360 mg.
Step-by-step explanation:
The medicine has a decay rate of 40% in 25 hours, which means after 24 hours its amount will be 100% - 40% = 60% it's original value.
Let us call the number of hours passed and the number of 24-hours passed, then we know that
.
Now, the amount of medicine left after time (<em>d</em>th 24-hour) will be
and since , we have
We now use this equation to find the final amount after :
Volume of a cylinder = πr²h
where,
r is the radius of the cylinder
h is the height of the cylinder
Area of the rectangle = length X breadth
We can consider that a rectangle if rotated will form a cylinder.
In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
