One serving provides 3.2 milligrams of niacin to John.

Given: One serving provides 20% of the recommended daily allowance of niacin.

Recommended daily allowance is 16 milligrams

What is the percentage?

The percentage is the way of depicting a value concerning the one-hundredth part of any quantity. The symbol of percentage is %.

For example, 20% means 20 in the parts of 100. 20% means 20 / 100 or 0.20.

Now let’s solve the given problem.

Recommended daily allowance of niacin = 16 milligrams

One serving provides 20% of the daily allowance.

So, the number of milligrams provided by one serving is 20% of the recommended daily allowance of niacin.

= 20% of 16 milligrams

= 20 / 100 * 16 milligrams

= 0.20 * 16 milligrams

= 3.2 milligrams.

Therefore, the milligrams of niacin provided is 3.2 milligrams.

Hence, one serving provides 3.2 milligrams of niacin to John.

 width of surrounding rings=y

   solution:
   Radius of the circle=x+4y
Area of the outermost ring=Area of the circle-Area of the penultimate ring =Ď€(x+4y)^2-Ď€(x+3y)^2
=Ď€(x^2+8xy+16y^2-x^2-9y^2-6xy)
 =Ď€(2xy+7y^2)
 hence the area of the outermost ring in terms of x and y is Ď€(2xy+7y^2).</span>
