Answer:
<h2>P = 40.56 ft</h2>
Step-by-step explanation:
We have three sides of a rectangle, and a semicircle.
Three sides of a rectangle: 10ft + 8ft + 10ft = 28ft.
The circumference of a whole circle: C = π(8) = 8π ft.
The semicircle: 8π : 2 = 4π ft
Using π ≈ 3.14 → 4π ≈ (4)(3.14) = 12.56 ft
The perimeter of the figure: P = 28ft + 12.56ft = 40.56ft
I think the answer for the first one is 10 feet because i took the ten feet measurement and compared it to the B-C and it matched and for the second one its 15 feet because i took the measurement again and compared it to A-B and it matched so i think that is the correct answer
#1= 10 FEET
#2= 15 FEET
No it’s not -7 it’s = 2x + 20
i hope it helps!
B. 9x because 3+3+3 would equal 9
