Answer 2

Explanation:

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

hope this helps you ☺️
