Given:
- Height of cylinder is 18.2 cm
- Radius of cylinder is 3 cm
To Find?
- Surface area
Solution:
Using formula:
- Surface area of cylinder = 2πr (h + r)
Substituting values in the formula:
- Hence, (B) 399.4 cm² is right answer.

Answer:
h must be equal to - 2.
Step-by-step explanation:
See the attached graph.
The original function ........... (1) is plotted in the graph denoted by the blue curve.
And the translated curve to the original function i.e. ............ (2) is plotted in the graph denoted by the red curve.
Now, the blue curve passes through the point (0,1) point and the red curve passes through the point (-2,1) point.
Therefore, the x-coordinate gets reduced by 2 units in the translated curve corresponding to a certain y-coordinate.
Therefore, h must be equal to - 2. (Answer)

Answer:
Second option is correct. The x-coordinate of the point that divides the directed line segment from J to K into a ratio of 2:5 is -2.
Step-by-step explanation:
From the given graph it is noticed that the endpoints of the line segment JK are J(-6,-2) and K(8,-9).
The formula to find x intercept.
The ratio is 2:5, therefore the value of m is 2 and the value of n is 5.
Therefore the x-coordinate is -2 and second option is correct.
