This is a simple right triangle problem.
a^2 + b^2 = c^2
the hypotenuse (or c) is 9 +x
and a is x
And b is 15
So so we sub in the values
x^2 + (15)^2 = (9+x)^2
x^2 + 225 = x^2 + 18x + 81
144 = 18x
8 = x

Answer:
<h3>
The cylinder's radius is <u> 2 </u> inches </h3><h3>
and it’s height is <u> 3 </u> inches.</h3>
Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in
