HEL PL IT IS DUE AT 3:15 PM If the diameter of the circle above is 22 in, what is the circumference of the circle?
A.
11 in
B.
22 in
C.
44 in
D.
121 in

B. 22 in ?

Step-by-step explanation:

circumference of the circle: 2πr

2 × π × 11 = 22π in

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
