A=adult tickets
c=chlderenticekts
s=sinior tickets
a=c
a+c+s=120
2a+s=120
total made is 1100
12a+6c+10s=1100
sub
a=c
12a+6a+10s=1100
add
18a+10s=1100
multiply first equation by -9 and add to other equation
-18a-9s=-1080
18a+10s=1100 +
0a+s=20
s=20

The volume of the sphere is 113.04 inches³.
We should know about the volume of sphere formula, which is given by:
V = 4/3 x π x r³
V is the volume of the sphere and r is the radius of the sphere.
According to the question, the parameter of the sphere is given by :
r = 3 inches
π = 3.14
By substituting the parameter of radius, we can calculate
V = 4/3 x π x r³
V = 4/3 x 3.14 x 3³
V = 4.186 x 27
V = 113.04
Hence, the volume of the sphere is 113.04 inches³.
