Answer:
13.5 in, or 34.3 cm.
Step-by-step explanation:
First, use the formula volume = pi * r^2 * height- you have the volume, so just solve the equation 411pi = pi * 9 * r^2 for r, and you get that r = 6.75. Since diameter is equal to 2r, multiply 6.75 by 2 to get your answer of 13.5 inches. The questions asks for the diameter in centimeters though, which makes it 34.3 cm.

Answer:
<h2>B) x = 2/3</h2>
Step-by-step explanation:
y = a - horizontal line (a - any real number) - slope = 0
x = a - vertical line (a - any real number) - undefined slope
y = mx + b - diagonal line (m - any real number except 0, b - any real number) - m - slope
