Given
The diameter is given 18 cm.
Explanation
To determine the volume of sphere,
Use the formula,
[tex]V=\frac{4}{3}\pi(r)^3[/tex]
Find the radius from the diameter and radius relation.
d=2r
Substitute the value of diameter and find radius.
[tex]\begin{gathered} 18=2r \\ r=9cm \end{gathered}[/tex]
Now find the volume of sphere.
[tex]\begin{gathered} V=\frac{4}{3}\times3.14\times9^3 \\ V=3052.08cm^3 \end{gathered}[/tex]
Answer
Hence the volume of sphere is 3054 cubic cm . (approx)
The correct option is A.
