## anonymous 5 years ago how do you find surface area of a cylinder??

1. anonymous

think about doing the surface area of the outside, plus the surface area of the top and bottom

2. anonymous

so, the area of a circle is $2\pi r^2$

3. anonymous

2??

4. anonymous

sorry, thats for both ends

5. anonymous

oh because theres 2 circles oh ok

6. anonymous

then the circumference of a circle is $2\pi r$ and you will multiply that by the height to get the surface area of the rest of the cylinder.

7. anonymous

ok cool thanks for your help I will fan you

8. anonymous

no problemo. and remember that you have to add the areas. area of ends + area of rest of cylinder.

9. anonymous

yup..
