Question

what is the value of the sphere? Round the answer to the nearest cubic unit.A.3,054cm^3B.339cm^3C.763cm^3D.9,160cm^3

Answer 1

Given

The diameter is given 18 cm.

Step-by-step explanation

To determine the volume of sphere,

Use the formula,

`V=(4)/(3)\pi(r)^3`

Find the radius from the diameter and radius relation.

d=2r

Substitute the value of diameter and find radius.

`\begin{gathered} 18=2r \\ r=9cm \end{gathered}`

Now find the volume of sphere.

`\begin{gathered} V=(4)/(3)*3.14*9^3 \\ V=3052.08cm^3 \end{gathered}`

Answer

Hence the volume of sphere is 3054 cubic cm . (approx)

The correct option is A.
