    Answer:

    curved surface area(CSA) = 1257.14285714

    Total Surface Area(TSA) = 1414.28571428

    volume of cylinder(V) = 3142.85714285

    Step-by-step explanation:

    GIVEN:

    Height(h):40

    Radius(r):5

    We know that,

    curved surface area(CSA) = 2πrh

    CSA = (2×22×5×40)÷7

    CSA = 8800÷7

    CSA = 1257.14285714

    We know that,

    Total Surface Area(TSA) = 2πr(h+r)

    TSA = (2×22×5(40+5))÷7

    TSA = (220×45)÷7

    TSA = 9900÷7

    TSA = 1414.28571428

    We know that,

    volume of cylinder(V) = πr²h

    V = (22×5×5×40)÷7

    V = 22000÷7

    V = 3142.85714285

    Step-by-step explanation:

    CSA=2πrh

    =2×22/7×5×40

    =22/7×5×20

    =22/7×100

    =3.14×100

    =314

    volume=πr^2h

    =22/7×25×40

    =22/7×1000

    =3.14×1000

    =3140
