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
Answer: A
Step-by-step explanation:
The solution to the inequality is x <= -5 and x>=-3 so A is correct
The answer is 16%. 4/25=0.16
5X -3X > 4
2X > 4
X > 2
the only viable answer is D
