1st consider the volume of cylinder by its formula then you find its volume is 5390.0 cm sq. then you find volume of 1st hole by using fomula of volume of cone i.e 64.68 6cm sq llly you find volume of 2nd hole 234.66 cm sq. then you substract values of both from volume of cylinder ans. is 5090.66 cm sq. if my ans. is false then I am sorry &also you tell my faults
