A circular pool is surrounded by a circular walkway. The radius of the pool is y − 4 and the radius of the full circle formed by

TiliK225 [7]

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

Please help show work<br><br> 3√(125) -√(16) = ?

Anna007 [38]

First, simplify the radicals
√125=√(5*5*5)=(√5*5)(√5)=5√5
so 3√125=3*5√5=15√5

and √16=4
so
15√(5)-4 is the simplified version

Which number produces an irrational number when added to 5/8?

givi [52]

Choice D will create an irrational number when added. This is because a rational number plus a rational number will always be irrational (you can experiment this by trying to add rational numbers to pi). For example, 3 + pi = 6.1415926..... or $1+ \frac{2}{7} =1.285714...$ .
