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(4^{2}) 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

Answer:

x = 4

Step-by-step explanation:

You begin by making what is inside the brackets = 0. In other words you will somehow get 0 * brackets + 3 = 3

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4. When you make x = 4, the inside of the brackets = 0

1/2 * 0 = 0

So you are left with

3 = 0 + 3

and x has been made = 4

Do what's in the brackets before anything else.
