Answer» Radius of cylinder = 13 cmStep-by-step explanation:Given that:Height of cylinder = 15 cmCurved surface area of cylinder = 1226 cm²To FIND:Radius of cylinder. Formula used in SOLVING cylinder problems:C.S.A. = 2πrh sq. unitT.S.A. = 2πr(r + H) sq. unitVolume = πr²h cubic unitWhere, C.S.A. = CURVED Surface AreaT.S.A. = Total Surface Arear = radiush = heightπ = 22/7 or 3.14Here, To find the radius of cylinder we have to use C.S.A. formula:1226 = 2πr × 15→ πr = 1226/30→ r = (1226 × 7)/(30 × 22)→ r = 13 (approx.)∴ Radius of cylinder = 13 cm
