Answer:
A
Step-by-step explanation:
The diameter is 2πr or 4032π in this. The arc from B to C counterclockwise is 130° out of 360°. 130/360 multiplied by 4032 is 1456
b
v= 141.3
v= pi × r^2 × h
v= 3.14 × 3^2 × 5
v= 3.14 × 9 × 5
v=141.3
18
2x9=18
the increase is by 2
You can add 17 plus 2 or subtract 17 from 19.
