Answer:
6 meters of Flooring.
Step-by-step explanation:
I could be wrong but I’m pretty sure this question is Length x Width to find the Area of the “Room” or “Triangle.”. <3
A=πr²
pool=π(y-4)²=π(y²-8y+16)
total=π(y+4)²=π(y²+8y+16)
walkway=total-pool
walkway=π(y²+8y+16)-π(y²-8y+16)=
π(y²+8y+16-y²+8y-16)=
π(16y)=
16πy
first option is answer
