Answer:
AREA OF TOP CIRCLE OF CYLINDER=154 sq. Units
C.S.A. of the cylinder=880 sq. units
According to question:
we have to find out first:
Area of top circle=154 sq. units
=> πr²=154
=>22/7 × r²=154
=>r²=154×7÷22
=>r²=49
=>r=√49 = 7
Than we have to find C.S.A.=880 Sq. units
=>2πrh=880
=>2×22/7×7×h=880
=>44/7h=880
∴hence h = 880/44 thats = 20
