Answer:where is the question??.?
Step-by-step explanation:
Answer:
P’(-1, 1), I’ (1, 2), G’(1,0)
Step-by-step explanation:
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
2 hours per hour cause 1/4=15 min 1/2 times 4 equals 2 so 2 miles per hour
