it's also the wrong calculation. πr² is the formula for computing the area of a two-dimensional circle. But this is in 3D, so we should be computing the volume of a sphere, which is (4πr³)/3. Using that formula we can conclude that a 24% increase in the radius of a sphere results in a 90.68% increase in volume.
