Question

the curved sutade area of a cylinder is pi(2y²-18y+40) and its height is (y - 4) then find its​

Answer 1

Answer:

Given, curved surface varea of cone =1760 sq.cm and radius =14 cm

We know, curved surface area of a cylinder of radius "R" and height "h" =2πRh

Hence, curved surface area of the given cylinder =2×

22

×14×h=1760sq.cm

∴h=20 cm
