[tex] Dimensions \:of \:a \: cylinder : [/tex]
[tex] Height (h) = 10 \:cm ,\\Radius \:of \:the \: base (r) = 7cm [/tex]
[tex] curved surface area of cylinder(A) = 2\pi rh \\= 2 \times \frac{22}{7} \times 7 \times 10 \\= 2\times 22 \times 10 \\= 440 \:cm^{2} [/tex]
Therefore.,
[tex] \red {curved surface area of cylinder} \green { = 440 \:cm^{2}} [/tex]

Answer:
Curved surface area of cylinder=2πr×height(here r is Base)
Curved surface area=2×22/7×7×10
=44/7×70
=440cm^2
