Answer:
1. ![Area = 28.26](https://tex.z-dn.net/?f=Area%20%3D%2028.26)
2 and 3: See explanation
Step-by-step explanation:
Solving (1)
--- radius
The area is:
![Area = \pi r^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cpi%20r%5E2)
![Area = 3.14* 3^2](https://tex.z-dn.net/?f=Area%20%3D%203.14%2A%203%5E2)
![Area = 28.26](https://tex.z-dn.net/?f=Area%20%3D%2028.26)
There are no enough information to solve (2) and (3) as the radius and/or diameter are not provided.
However, the following formula will be used to calculate the required areas.
--- same process as (1)
Answer:
265
Step-by-step explanation:
It's a cube, so all sides are the same, so 6.5 x 6.5 x 6.5
This equals 264.625. They want 3 significant figures, so u round to the nearest whole number. Significant numbers are whole numbers. This becomes, 265.
Answer: and the answer is 2x + 7
Step-by-step explanation:
as it is a polynomial in one variable, it has only one solution.
Hope it helped u,

71 degrees you add 82+27= 109 then 180-109=71
Answer:
-48x+16
Step-by-step explanation:
-8(6x - 2) first multiply each term in the parentheses by 8 to get -8x6x-8x(-2) and calculate the product to get your answer which is -48x+16
