Answer:
Step-by-step explanation:
What we're looking for here is the volume of this ball, which is the volume of a sphere:

If our diameter is 3, then the radius is 1.5:

In terms of π, the solution is
which can also be expressed as 
Or if you have to multiply in the pi, the solution is
V = 14.14 cubic inches
Answer:
Step-by-step explanation:
ok so this is what you would do
5s+3t=30
-1(2s+3t=-3)
which will become
5s+3t=30
-2s-3t=3
which turns into
3s = 33, s=11
F(4)=(4-1)+2*4=11...
This seems a bit too easy though, did you mean f(n)=f(n-1)+2n ? In this case :
f(1)=16
f(2)=16+2*2=20
f(3)=20+2*3=26
f(4)=26+2*4=34
Answer:
2:30
Step-by-step explanation:
58+32=90
90-60=30
2:30 is the answer
Answer:
