<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>
Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get

It can be written as

The required equation is
.
Therefore, the correct option is B.
