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.
the answer is A.0 because 0 devided by a number iz zero
Answer:
x = 15
Step-by-step explanation:
Given
2 = - 
+ 
x
Multiply through by 4 to clear the fractions
8 = - 7 + x ( add 7 to both sides )
15 = x
Answer:
12
Step-by-step explanation:
2/3 x + x = 20
2/3 x + 3/3x = 20
5/3 x = 20 ... times 3/5 both sides
x = 12
check: 2/3 x 12 + 12 = 8 + 12 = 20
