ok so V=(4/3)pi(r^3) V=288pi therefor 288pi=(4/3)(pi)(r^3) divide both sides by pi 288=(4/3)(r^3) multiplyboth sides by 3/4 (4/3 times 3/4=12/12=1 and 1 times r^3=r^3) 864/4=r^3 216=r^3 cube root both sides 6=r radius=6 units area=4pir^2 area=4pi6^2 area=4pi36 area=144pi radius=6units area=144pi square units
