16b^6 sqrt 6a would be the answer
F(r) = 3.14r^2....and ur looking for f(5)....so basically all u do is sub in 5 for r.
f(5) = 3.14 * 5^2
f(5) = 3.14 * 25
f(5) = 78.50 <===
Sent a picture of the solution to the problem (s).
The 35% is 81.90 plus the 234. So your answer would be $315.90 is the original price. If you need me to explain it let me know :)
1/10 in decimal form is .1
