Question

find the radius of the cylinder whose lSA is 968cm and height of cylinder is 7cm
​

Answer 1

Step-by-step explanation:

lateral surface area =

$2\pi \: rh$

let radius = r

968 cm² = 2 × 22/7 × radius × height

968 cm² = 2 × 22 × radius

968 cm² = 44 × radius

44 × r = 968 cm²

r = 968

44

r = 22

therefore radius=22
