    Given:

    • Diameter of the cylinder = 14m
    • Height(depth) of the cylinder = 10m

    To be found:

    The Curved Surface Area (CSA) of the cylinder.

    \star The formula for finding the Curved Surface Area of a cylinder is

    = 2πrh unit sq.

    [∵ In which ‘r’ is the ‘radius’ and ‘h’ is the ‘height’ of the cylinder.]

    But we need a radius instead of diameter.

    We know that twice the radius is equal to the diameter, or half of the diameter is equal to the radius.

    ∴ Diameter = 2 × Radius

    OR

    Radius=\frac{Diameter}{2}

    So,

    ⇒ 14 = 2r

    ⇒ 14 ÷ 2 = r

    ⇒ 7 m = r

    So, Radius if the cylinder is 7m.

    Now,

    Curved Surface Area of the cylinder

    = 2 \times \frac{22}{\not{7}} \times \not{7} \times 10

    = 2 \times 22 \times 10

    \boxed{= 440\ m^{2}}

    Hence,

    The Curved Surface Area (CSA) of the cylinder is 440 m sq.

    Answer:

    curved surface area =2πrh

    Step-by-step explanation:

    diameter of following cylinder=14

    : . Radius=7

    height=10

    : .curved surface area=2×22/7×7×10

    =2×22×10

    =440cm^2
