Question:
If the curved surface area of a cylinder is \( 1760 \) cm\(^2\) and its base radius is \( 14 \) cm, then its height is:
If the curved surface area of a cylinder is \( 1760 \) cm\(^2\) and its base radius is \( 14 \) cm, then its height is:
Show Hint
For cylinders, Curved Surface Area formula:
\[ \text{CSA} = 2\pi rh \]
\[ \text{CSA} = 2\pi rh \]

The Correct Option is C
Solution and Explanation
Curved surface area of a cylinder:
\[ \text{CSA} = 2\pi rh \] \[ 1760 = 2\pi (14) h \] \[ 1760 = 2(3.14)(14) h \] \[ 1760 = 87.92 h \] \[ h = \frac{1760}{87.92} \approx 20 \text{ cm} \]
\[ \text{CSA} = 2\pi rh \] \[ 1760 = 2\pi (14) h \] \[ 1760 = 2(3.14)(14) h \] \[ 1760 = 87.92 h \] \[ h = \frac{1760}{87.92} \approx 20 \text{ cm} \]

- One day the old emperor Shah Jahan became ill. His son Aurangzeb, who always wanted to be the emperor, put his father in a jail. Jahanara Begum, the eldest child of Shah Jahan, did not leave her father and went to jail along with him. She said, “I shall share the suffering of my father.
