Perimeter = 2 × π × r
Perimeter = 2 × 3.14 × 9
Perimeter = 56.52
Perimeter = 56.52 ÷ 2
Perimeter = 28.26
The perimeter of a semicircle with a radius of 9mm is 28.26
The equation for this is y= -5/6 x +22/6
Answer:

Step-by-step explanation:
Note that when you multiply two negative numbers, the answer will result as a positive number. Also note that when you multiply a negative number with a positive number, then your answer will result in a negative number.
(-1)(-1) = 1
(1)(-3) = -3
-3 is your answer.
