<h3>Given:-</h3>
- radius = 7 inches
- height = 9 inches

<h3>To find:</h3>

we know:-


So:-
⇢SA of cylinder=2πrh+2πr²

⇢SA of cylinder = 2πr(h+r)

⇢SA of cylinder = 2 × π × 7(7 + 9)

⇢SA of cylinder = 2 × π × 7 (16)

⇢SA of cylinder = 2 × π × 112

⇢SA of cylinder = 2 × 112 × π

⇢SA of cylinder = 224π inches ²

.°. <u>Surface</u><u> </u><u>Area</u><u> </u><u>of</u><u> </u><u>cylinder</u><u> </u><u>is</u><u> </u><u>224π inches</u><u>²</u><u>.</u>
