Question

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

Answer 1

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