What is the total surface area of a cylinder having a radius of 3.5 cm and height 5.5 cm?

211.5 cm²
198 cm²
121 cm²
None of these

Explanation

we use the formula:

$Total Surface Area = 2 π r (h + r)$

Where:

$r$ is the radius of the cylinder.
$h is the height of the cylinder.$

Radius $r = 3.5 , text{cm}$
Height $h = 5.5 , text{cm}$

Plug values into the formula:
$Total Surface Area = 2 π \times 3.5 \times (5.5 + 3.5)$ $= 2pi times 3.5 times 9$ $= 2 \times 3.1416 \times 3.5 \times 9$ $= 2 \times 3.1416 \times 31.5$ $= 6.2832 \times 31.5$ $\approx 198.0 cm^{2}$
