Hello!

- Diameter of the circle = 12 cm

Area of the Circle

A=πr²
Hey! We have the diameter, not the radius.
Don't panic. In order to find the radius, we should divide the diameter by 2.
So, the radius is 6.
Plug it into the formula:
A=π(6)²
A=π(36)
A≈113 cm
Hope it helps!
Good luck and enjoy your day!

Answer:
Step-by-step explanation:
5x + 3 = 2x - 6
3x + 3 = -6
3x = -9
x = -3
Answer:
y = (6/11)x + 13/11
Step-by-step explanation:
y = mx + c
m = (-1-5)/(-4-7) = -6/-11 = 6/11
y = (6/11)x + c
When x = 7, y = 5
5 = (6/11)(7) + c
5 = 42/11 + c
c = 5 - 42/11
c = 13/11
y = (6/11)x + 13/11
11y = 6x + 13

Answer:
a) The correct option is C: 4x
b) The correct option is B: 2x
Step-by-step explanation:
a) Usually when we have a real number multiplying a variable, we do not need to write the multiplication symbol.
So instead of writing:
4×x
We can write:
4x
And this will be equivalent.
Then in this case the correct option is C.
b) We know that if we have the multiplication of A by n, this will be equivalent to add A n times.
Then if we have the sum of A, for example, 4 times, we have:
A + A + A + A
And this can be written as 4*A
In this case, we have the expression x + x.
So we are adding x two times, then this can be written as: 2*x, or, as we said earlier, this also can be written as 2x.
Then the correct option is option B.
