Answer 1

GIVEN:-

If the lateral surface area of a right circular cyclinder of radius 3cm is 94.2sqcm, then the height of the cyclinder is

ẞØLÛTÏØÑ:-

$2\pi \: rh \: \\ = 94.2 \\ or \: \:2 \times \frac{22}{7} \times 3 \times h = 94.2 \\ or \: h = 94.2 \times \frac{7}{22 \times 6} \\or \: \: h = 5(approximate)$
