Volume of a sphere: (4/3)πr³
r=radius=9 in
Volume=(4/3)*π*(9 in)³=972π cubic inches≈3053.63 in³
answer: D) 972π cubic inches (3053.63 in³ is correct)

Answer:
Answer:
n=
19
/5
Step-by-step explanation:
3(n−5)=4−2n
Step 1: Simplify both sides of the equation.
3(n−5)=4−2n
(3)(n)+(3)(−5)=4+−2n(Distribute)
3n+−15=4+−2n
3n−15=−2n+4
Step 2: Add 2n to both sides.
3n−15+2n=−2n+4+2n
5n−15=4
Step 3: Add 15 to both sides.
5n−15+15=4+15
5n=19
Step 4: Divide both sides by 5.
5n
/5
=
