<h2><u>Answer</u>:-</h2>
<h3>Given:-</h3>
Radius (r) of the cylinder = 10 ft.
Height (h) of the cylinder = 6 ft.
<h3>To Find:-</h3>
The lateral surface area of the cylinder.
<h2>Solution:-</h2>
We know,
Formula of lateral surface area of cylinder is 2πrh.
So, Lateral surface area of the cylinder = 2 × 3.14 × 10 × 6
Lateral surface area of the cylinder = 376.8 = 377 sq. ft.
<h3>The lateral surface area of the cylinder is <u>3</u><u>7</u><u>7</u><u> </u><u>sq.</u><u> </u><u>ft</u>. [Answer]</h3>
