Step-by-step explanation:
r=28m
and the formula for the L.S.A of cylinder is 2πrh
T.S.A = 2πrh+ 2πr²=2πr(r+h)
by putting the value of r and tsa in formula
5805= 2×22/7×28(28+h)
5805= 44×4(28+h)
5805/44×4=28+h
33(app.)=28+h
h=5m
there for C.S.A=. 2×22/7×28×5
= 44×20
= 880m²
so this was the correct answer
hope you will mark it as brainliest
