This tells you how to find the volume of a rectangular prism.

Cylinder Volume and Volume Problems

Outside:

d/2= r

1/2= r

0.5m= r

V= π x r x r x h

V= (3.14 x 0.5 x 0.5) x 10

V= 0.785m^2 x 10m

V= 7.85m^3

Inside:

d/2= r

0.8/2= r

0.4m= r

V= π x r x r x h

V= (3.14 x 0.4 x 0.4) x 10

V= 0.5024m^2 x 10m

V= 5.024m^3

7.85m^3 - 5.024m^3 = 2.8m^3

I liked your pictures! Next time add some color to your text.

ReplyDeleteGreat post Kim. Your post was very neat and well explained.

ReplyDeleteGood post Kim. Next time, add more colors to your post. Other than that great job!

ReplyDeleteGreat job Kim. Your post was very neat and it was really easy to understand. I also liked how you bolded the answers because there were no colors. I think you have the same problem as me. I can't put any colors on my posts either. Great job.
