Answer:
B
Step-by-step explanation:
When finding the area of a circle you have to use the formula
Area= Pie x radius^2
Radius=8.5
So you have to plug that into the equation.
8.5x8.5=72.25
72.25x3.14=226.87
So Area is 226.87
So your answer is B
Don’t go to that guys link, it’s a skam and you will get a virus.
3x2 -3 -x2 +7x -10 =2x2 +7x -13
so thats (2)
The answer is 7 because honestly I just don’t know what to put
5+2x2x2÷4-2
= 5+[(2x2x2)÷4]-2
= 5 + [8 ÷4 ] -2
= 5 + 2 - 2
= 5
