Answer:
Step-by-step explanation:
For question 3, area is pi times radius squared. I would do 8 divided by 2 to get radius of 4. Then do 3.14([tex]4^{2}[/tex]) and round to get your answer.
Yes, question 5 is height times length times width, which would be (13)(5)(6) to get 346 s squared. let met look at the rest
Question 8 is v=lwh but you have the base area. So you would do area times height which is (12)(8), which gets you the answer as 96 cm cubed
Question 7 you need to find the surface area, surface area is (l)(w)(h), so (8)(2)(2), so 72 should be your answer
