Answer:
Step-by-step explanation:
The area of a circle is :A= π r² r : the radius
A= 8π square units
so : π r² = 8π
r² = 8
r = √8 = √(4 × 2) =√4×√2
r = 2√2 units
I believe no, it would have to be x = -6.5
Decimal place value starts with the first number to the right of the decimal. The first number is called the 10th, the second value is the 100th, third is the 100th place and so on. For example, on your paper number 5) says round to the nearest whole number. When it is a five, it is half way between. Therefore, you are always going to treat it as if it were a 6. That will make you new equation
3.6
Because .6 would be closer to another whole number (meaning
+1) your answer will be 4.
If you look at number 6) they want you to round to the nearest 100th (second place to the right of the decimal.)
because the last 2 is closer is closer to 0 on a number scale (1, 2, 3, 4, ...) you would just leave it as is with out the last 2 on the end though.

Answer:
Since all triangle angles add up to 180°, you can set all the angles equal to 180.
(96 + 2x + (x + 12)) = 180
You can now simplify it together
108 + 3x = 180
Now you can isolate x by itself
180 - 108 = 72
72 / 3 = 24
x = 24
Volume: L x W x H
L = 1
W = 1
H = 2
1 x 1 x 2 = 2
The volume would be 2 cubic feet
