Question

The diameter of a cylinder is equal to its height. If the height of the cylinder is 14 cm, find the total surface area of the cylinder.(Take ∏=22/7)

• A. 616 cm²
• B. 1232 cm²
• C. 924 cm²
• D. 2164 cm²

Answer 1

Answer:

C. 924 cm²

Given:

• Height (h = 14) cm

• Diameter = height ⇒ (d = 14) cm ⇒ (r = 7) cm

  Total Surface Area (TSA) of cylinder:

$\text{TSA} = 2\pi r (r + h)$

Substitute values:
$= 2 \times \frac{22}{7} \times 7 \times (7 + 14)$
$= 2 \times 22 \times 21$
$= 44 \times 21 = 924$
Final Answer:

$\boxed{924 \text{ cm}^2}$
