Surface of the cylinder : 2*(pi*radius^2)+(2*pi*radius*height)=2(pi*1.5^2)+(2*pi*1.5*9)=31.5pi cm^2 ~99 cm^2
Volume : pi*radius^2*height=pi*1.5^2*9=20.25pi~64 cm^3

Answer:
x = 5/9
Step-by-step explanation:
1/3 +x = 8/9
We need to get a common denominator of 9
1/3 * 3/3 +x = 8/9
3/9 + x = 8/9
Subtract 3/9 from each side
3/9 - 3/9 +x = 8/9 - 3/9
x = 5/9
Answer:
(7, 5) no
(-6, -3) yes
(-5, 2) no
(1, -4) no
Step-by-step explanation:
For this question we have to input the x and y values into the equation: 2x - 9y = 15
For (7, 5) we would get 14 - 45 = 15 which is false so it is not a solution.
For (-6, -3) we would get -12 + 27 = 15 which is true so it is a solution.
For (-5, 2) we would get -10 - 18 = 15 which is false so it is not a solution.
For (1, -4) we would get 2 + 36 = 15 which is false so it is not a solution.
