Question

I really need help with this its due todayyy
​

Answer 1

I will answer a few questions so you can apply the same logic to the others

The volume of a sphere =
`(4)/(3)` π
`r^(3)`

1.

We can see that the radius of the sphere is 5cm

Substitute the value into the equation for volume and solve for V

V =
`(4)/(3)` * π *
`5^(3)`

V = 523.6
`cm^(3)`

4.

The diameter is given to us as 6km. To find the radius we take half of this, 3km

Substitute the value into the equation for volume and solve for V

V =
`(4)/(3)` * π *
`3^(3)`

V = 113.1
`km^(3)`

Hopefully that helps you with completing the rest!
