Answer:
I will answer a few questions so you can apply the same logic to the others
The volume of a sphere = [tex]\frac{4}{3}[/tex] π [tex]r^{3}[/tex]
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 = [tex]\frac{4}{3}[/tex] * π * [tex]5^{3}[/tex]
V = 523.6 [tex]cm^{3}[/tex]
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 = [tex]\frac{4}{3}[/tex] * π * [tex]3^{3}[/tex]
V = 113.1 [tex]km^{3}[/tex]
Hopefully that helps you with completing the rest!
