A solid right circular cylinder has radius of $14$ cm and height of $8$ cm. Find its total surface area.

Open in App

Solution

Given, radius $r = 14$ cm, height $h = 8$ cm
Total surface area of cylinder $= 2 π r (h + r)$ sq.units
$= 2 \times \frac{22}{7} \times 14 (8 + 14)$
$= 2 \times \frac{22}{7} \times 14 \times 22$
$= 1936$ sq.cm.
