plz help
The radius of a cylinder is 3.5 ft. The height is 14 ft. Find the surface area and volume of the cylinder to the nearest tenth of a foot. Show your work.

Answer 1

the main thing to know is that all a cylindar is is two circles and a rectangle bent into a circle.
you know the formula for a circle is A=pi*r^2
the only other part is the rectangle.
You know the height is 14 so what's the width

Answer 2

idk

Answer 3

the width is the circumference of the circle, C = 2*pi*r

Answer 4

so what you have is 2 circles and a rectangle
2*pi*r^2 + h*(2*pi*r) = surface area

Answer 5

oh ok

Answer 6

hopw that makes some sense

Answer 7

hope*

Answer 8

thank

Answer 9
