The correct answer is 7r/s
Answer:
A. 244.93 ft sq
Step-by-step explanation: radius= 7 pi= 3.14 area for triangle= 168 area for semi-circle = 76.93.
how i got it:
area of semicircle 7 x 7 =49 49 x 3.14 = 153.86 153.86 divded by 2 = 76.93
area of triangle: 14 x 24 = 336 336 divded by 2 = 168 168 + 76.93 = 244.93
5 people , 1 wall ~ 20/5 = 4 minutes
1 person, 1 wall ~ 4/5 minutes
9 people, 1 wall ~ (4/5) x 9 = (36/5) minutes
Therefore 9 people, 9 walls ~ (36/5) x 9
= 64.8 minutes
= 1h 4 min 48 s
