d÷2 = r
8÷2 = r
8÷2 = 4cm2
(2 x 3.14 x 4 x 4) + (2 x r x 3.14 x 15)
100.48cm2 + 376.8cm2

Good job !
ReplyDeleteI really like how you drew pictures for both questions . I have a suggestion. For the area a the end, you should put TSA or total surface area . Other than that you did a good job .
Good job Richard! Your pictures for both questions were very neat. So was the way you laid everything out. I also like your font size because it was really easy to see and your colour choices were good as well. I agree with Allison, always remember to have TSA written with your final answer. Everything was well done, keep up the good work!
ReplyDeleteGood job Richard, I liked your pictures they stood out very well. Also way to make the answers stand out, and the formulas too. For improvenets maybe make your use of space a bit better, space the out neater and make sure the things that belong together look like they belong together, by using italics, bold or colours and even font sizes. Make some more things stand out like "Cylinder" and add something to help us out. Anyways, great post keep working hard and keep up the good work.
