Here's the formula you need to use:
The volume of any cylinder is = (pi) x (radius)² x (height) .
Take that formula.
Write your "3 inches" in place of "radius".
Write your "12 inches" in place of "height".
Write "3.14" in place of "pi".
Do the arithmetic, and bada-bing, you'll have the volume.
Answer: Z = 0.9y - 20
_______
4
Step-by-step explanation: First, add (-20)/3 to both sides. Then, divide both sides by 4/3.
Exaxt form
-5.45*10^4
Decimal Form
-54500
A = a^2
112 = a^2
sqrt 112 = a
sqrt 16 * sqrt 7 = a
4 sqrt 7 = a
so 4 sqrt 7 is the length of each side
