                                                how to find the surface area of a cylinder

here is a website you can go to so you can learn more about finding surface areas

and here is a video on how to find surface areas

i hope this post helps you out. i am sorry for the late upload

Volume

                                                 

Volume of a triangular prism = area of the base x the height

AB=3 x 5/2

AB=15/2

AB=7.5

7.5 x 8.5=63.75 m 3

Volume of a rectangular prism = length x width x height

20 x 8 x 16 = 2560cm 3

Volume of a triangular prism=area of the base x height

AB=4 x 8 / 2

AB=32 / 2

AB=16cm 2

16 x 6.5 = 104 cm 3

0.375 x 104 = 39 cm 3

Volume of a cylinder = area of the base x height

d / 2 = r

12 / 2 = r

6 = r

pi x r 2 x h

3.14 x 6 2 x 15

3.14 x 36 x 15

1695.6 cm 3

here is a website you can go to so you can review volume. i hope this helps
