The answer is 1.64 feet. 1.64 x 12 = 19.68 inches
19.68 x 2.54 cm= 49.9872 cm
Y= -2/6 +4 theyre decreasing because the slope is negative
5
8
6 or 7
Just taking a guess
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
y=10+x(0.5)
This is the way of writing that equation.
