Circumference of circle = 2πr
220 = 2×22/7×r
r = 220×7/44 = 35
r = 0.35m
Height of cylinder = 2m
CSA of cylinder = 2πrh
= 2×22/7×0.35×2 =4.4m²
220 = 2×22/7×r
r = 220×7/44 = 35
r = 0.35m
Height of cylinder = 2m
CSA of cylinder = 2πrh
= 2×22/7×0.35×2 =4.4m²

lateral surface area =2π x R (radius) x H (height)
if diameter = 220 cm then radius = 110 cm
height =2 m ,convert it into cm that is = 200 cm
put all the values in formula :
lateral surface area = 2π × 110 × 200 = 13860 cm
hope u like it
