Sagot :

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.
