Question:

The base radius and height of a right circular cylinder are 5 cm and 10 cm. Its total surface area is

Options:

150π cm²

300π cm²

150 cm²

300 cm²

Correct Answer:

150π cm²

Explanation:

The correct answer is Option 1: 150π cm²

Total surface area = 2πr (h + r) 

  • $r$ = base radius = $5\text{ cm}$

  • $h$ = height = $10\text{ cm}$ 

= 2π 5 (10 + 5) = 150π cm².
