The radius is 7 what it is telling you is that you already did the square 4^2*3.14=49 pi.
Answer:
127
Step-by-step explanation:
3 x 7 + 5 - 2 - 3 + y
y = 106
3x7 = 21
21 + 5 = 26
26 - 2 = 24
24 - 3 = 21
21 + 106 = 127
The answer is negative because, ( -81/-9) =(+9). -(+9) = -9. Maybe for got the - sign before the equation
10 percent of 11.50 is 1.15. Subtract that from 11.50 and you would get 10.35. The sale price would be $10.35
