Question

How to find curved surface area and total surface area of of the cylindrical container whose base radius 8cm and height 42 cm?

Answer 1

By using the following formula,

$<b>Curved Surface Area = 2πrh</b>$

$2 × \frac{22}{7} × 8 × 42$

$2 × 22 × 8 × 6$

$2,112cm^2$

$<b>Total Surface Area</b>$ = $2πr^2$

$2 × \frac{22}{7} × 8 × 8$

$44 × \frac{22}{7} × 64$

$8,850.29 (approximately)$
