Answer:
Step-by-step explanation:
The perimeter is the arc length plus the two radius lines.
Arc length is:
s = (θ/360) 2πr
So the perimeter is:
P = (θ/360) 2πr + 2r
Given that θ=135 and r = 11:
P = (135/360) 2π(11) + 2(11)
P = 8.25π + 22
P ≈ 47.9
So the perimeter is greater than 47.5 cm.
Answer:
-9.5
Step-by-step explanation:
8.4×3=25.2
negative25.2- 5.7 equals negative 19.5 - 10. hey hi if my answer doesn't match with the answer in your book could you please tell me right away so that I can try another method or ask for help I would really like to help you bye.
Answer:
80 * 80% = 64 So it's not A
80 * 55% = 44 so it's not B
80 * 100% = 80 so it's not C
80 * 125% = 100 so D is your answer
