Answer:
100,000,000 goes 10 times into 1,000,000,000
Area of sector



so the area = 37.71 square metre
The first graphed rational number is at the middle of -2 and -1, thus the number represented is

The second graphed number is five out of six places from from 0 to 1, thus the number graphed is

The difference between the two numbers can be represented as

or

To find the difference,

Also,
Answer:
A: 18
Step-by-step explanation:
Hopefully this helps!
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r
V(new cylinder)= πR²h = π(3r)²h=9πr²h
V(new cylinder)/V(cylinder)=9πr²h/πr²h=9
Volume new cylinder 9 times more the volume of old cylinder.
