the mini pizza has diameter 6..so radius is 3

area of circle = $\pi r^2 = \pi (3)^2 = 9\pi$

the medium pizza has diameter twice the mini pizza so 12 is diameter..that means 6 is the radius

area of circle = $\pi r^2 = \pi (6^2) = 36\pi$

now it's asking the difference between the two so $36\pi - 9\pi$
