Question

Find the volume of a sphere with a diameter of 12 cm to one decimal place

Answer 1

Answer:2,715.4
`cm^(3)`

Explanation:

`\\`The formula for finding the volume of a sphere is give as

`(4)/(3)`
`\pi`
`r^(3)` , where r is the radius. To get the radius divide the diameter by 2 , that is

`\\` r =
`(12)/(2)`

`\\` = 6cm

`\\`substituting into the formula for calculating volume , we have

`\\`V =
`(4)/(3)`×
`(22)/(7)`×
`6^(3)`

`\\` =
`(19008)/(7)`

`\\`= 2715.4286

`\\`≈ 2715.4
`cm^(3)`
