Question

Find curved surface area of cylinder of height 10cm and radius of its base 7cm​

Answer 1

$Dimensions \:of \:a \: cylinder :$

$Height (h) = 10 \:cm ,\\Radius \:of \:the \: base (r) = 7cm$

$curved surface area of cylinder(A) = 2\pi rh \\= 2 \times \frac{22}{7} \times 7 \times 10 \\= 2\times 22 \times 10 \\= 440 \:cm^{2}$

Therefore.,

$\red {curved surface area of cylinder} \green { = 440 \:cm^{2}}$

Answer 2

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
