Question

The radius of a cylinder with
lateral surface area 440cm?
and height 14cm is​

Answer 1

LSA of cylinder=2πrh

440=2×22/7×r×14

440=44×r×2

440=88r

440/88=r

5=r

radius of cylinder is 5cm

please follow me

Answer 2

$\huge\underbrace\mathcal\pink{anSwer}$

LSA of the cylinder = 440 sq. cm

height of the cylinder (h) = 14cm

We know that,

LSA of the cylinder = 2πrh

=> 440 = 2 × 22/7 × r × 14

=> 440 = 2 × 22 × r × 2

=> 440 = 88r

=> 440/88 = r

=> r = 5 cm.
