Answer:
Step-by-step explanation:
Area of sector = angle/360 * pi * r^2
7.1 = 40/360 * 22/7 * r^2
7.1 = 1/9 * 22/7 * r^2
63.9 = 22r^2/7
r^2 = (7 * 63.9)/22
r^2 = 20.331818181818
r = square root of 20.331818181818
r = 4.51
d = r * 2 = 4.51 * 2 = 9.02
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
2(c+7)=2c+14
Use distributive property
2*c +2*7
2c+14=2c+14
