Step-by-step explanation:
assuming -16 is inside the radical
rad25-16 +7 subtract the radicals first
rad9+7 square 9
3+7

Answer:
Circumfrence: 40.21
Radius: 6.4
Step-by-step explanation:
For radius, you only have to divide the diameter (in this case 12.8) by 2 which gives us 6.4
For Circumference, plug in the radius in the formula C=2π(6.4), and that gives us 40.21
3 1/2 = 7/2
so y+7/2 = 6
y=6-7/2 = 12-7 / 2 = 5/2 = 2 1/2
2/3-5/6
2×2=4
3×2=6
4/6-5/6=-1/6
-1/6

3/4
