Answer:
12
Step-by-step explanation:
The formula for distance between points is 
So when you inserts the coordinates in this formula, it would be 



=12.08305
Usually, distance is round to whole number. So, it would be 12
The last answer is correct
-9T means -9 x T
So if T is equivalent to 4,
you should do:
-9 x 4 = -36
J= -36

V=(4/3)pir^3
4.5pi=(4/3)pir^3
divide both sides by pi
4.5=(4/3)r^3
times 3/4 both sides
3.375=r^3
cube root both sides
1.5=r
radius is 1.5cm
