Volume of a cylinder is area x height = pi r^2 h We want to find 'r'

v = pi r^2 h solve for 'r'

v/(pi h) = r^2

sqrt (v/(pi h) = r

sqrt (18488/(pi*23) = r = 15.995 m = ~ 16 m

Second one:

Area of cylinder pi r^2 = 36 pi

Volume she ate = area x 5 cm (the jar went from 11 cm to 6 cm = 5 cm)

= 36 pi x 5 = 565 cm^2 (and now Kelly has heartburn ! )
