Answer:
2
Step-by-step explanation:
The coefficient is the number in front of the variable.
So, in this case, the coefficient of n^2 is 6 and of n is 2.
The volume of a cylinder is V = pi*(r^2)*h and the lateral surface area is S = 2pi*r*h.
<span>In this case we must have V = pi*(r^2)*h = 90, so h = 90 / (pi*r^2). </span>
<span>Thus S = 2pi*r*(90 / (pi*r^2)) = 180 / r. So since S is inversely proportional to r we </span>
<span>will want the smallest possible radius for the cans as possible. </span>
<span>Now with r = 2 we require h = 90 / (pi*r^2) = 90 / (4*pi) = 7.162 inches, but since </span>
<span>this is greater than 5 inches we can't use this can radius. </span>
<span>With r = 2.5 inches we have h = 90 / (pi*(2.5)^2) = 4.584 inches to 3 decimal places, </span>
<span>resulting in a lateral surface area of S = 180 / 2.5 = 72 square inches.
