Whats the surface area of a cylinder w a radius of 1cm and height of 2?

I dont know but I Think you can ask your science teacher

Step-by-step explanation:

Approximately 18.84

Step-by-step explanation:

You know that a cylinder can be mapped out into 2 congruent circles and a rectangle with the length of the circumference and the height of the cylinder. So, you can find using pi*r^2 to find the surface area of 1 of the circles and multiply by 2 because there are 2 circles. That gives you 1^2= 1*3.14=3.14*2=6.28. Then find the circumference using 2pi*r. That goes into 2*3.14=6.28. The 6.28 you multiply by 2 to find the surface area of the rectangle. You add  it all together and obtain your answer.

its a straight line parallel to the time axis

what is the answer?
