The base radius and height of a right circular cylinder are 5 cm and 10 cm. Its total surface area is
150π cm²
300π cm²
150 cm²
300 cm²
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.
