Answer:
(2,0)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
we have
Substitute the value of x and the value of y of each point in the inequality and then compare the results
case a) (0, 2)
----> is not true
so
the point not satisfy the inequality
therefore
The point is not a solution of the inequality
case b) (2,0)
----> is true
so
the point satisfy the inequality
therefore
The point is a solution of the inequality
case c) (1, -2)
----> is not true
so
the point not satisfy the inequality
therefore
The point is not a solution of the inequality
case d) (-2, 1)
----> is not true
so
the point not satisfy the inequality
therefore
The point is not a solution of the inequality

C 12 minutes is the correct answer. Hope this helps :)
Answer:
= 1099 cm^2
Step-by-step explanation:
The surface area of a cylinder is found by using the formula
SA=2πrh+2πr^2
We know the diameter. To find the radius, we take the diameter and divide by 2.
r =d/2
r =14 cm/2 = 7 cm
h = 18 cm
Substituting what we know
SA = 2 * pi * 18 * 7 + 2 * pi * (7)^2
= 252 *pi + 2* pi *49
= 252 pi + 98 pi
= 350 * pi
Let pi be approximated by 3.14
SA = 350 * 3.14
= 1099 cm^2
620.388
I hope this is the right answer, im not
Sure if
You want me to change it to fractions percentages etc
