I have all the values like r= 0.475 but I can't figure out how to solve for H. I've tried division and multiplication. I'm so confused!
15m^2= 2 pi 0.475^2 + 2 pi 0.475* h
Thank you in advance! :)

Question 861272: My art students and I have an applied math question in the form of a word problem:
My art students and I are creating mosaics on 7 cylindrical concrete planters located at the front entrance of our school. The cylinder dimensions are H=24" and D=34.7" (OK to round up to 36"). We cannot imagine making these mosaics with 1" tiles, which would mean hand placing over 18,000 tiles on approximately 130 square feet of surface area, in the next two months! What is the largest tile width we can lay on these large cylinders which will appear to fit the surface of the cylinder. We are likely using glass tile and stained glass which are 1/8" thick. The tiles will be glued using Thinset mortar at about 1/16" thick. Once all tiles are in place, the mosaics will be grouted to weatherproof, fill gaps and unify the entire "look" of the image.
I recently spoke with a world-renowned mosaicist who created a similar-sized cylindrical mosaic. She told me she believes she was able to use tiles about 5-6" wide without having noticeable sharp edges sticking out.
I really appreciate your help!
Sincerely,
Julie Muellejans
