Front

If the radius of a sphere increases, what happens to its volume?

Back

The volume increases, as it is dependent on the radius.

Front

What is the formula for the volume of a sphere?

Back

V = 4πr³, where V is the volume and r is the radius.

Front

In the context of babysitting, if Dalton babysits more hours, what happens to his earnings?

Back

His earnings increase, as the amount of money earned is dependent on the hours babysat.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.
