<h2>The surface area of cylinder is 904.32 square meter</h2>

<em><u>Solution:</u></em>

<em><u>The surface area of cylinder is given as:</u></em>

S.A = 2 \pi r(h+r)

Where,

h is the height

r is the radius

From given,

h = 7 m

r = 9 m

<em><u>Substituting the values, we get,</u></em>

S.A = 2 \times 3.14 \times 9(7+9)\\\\S.A = 56.52 \times 16\\\\S.A = 904.32

Thus surface area of cylinder is 904.32 square meter
