Question

nice area of cylinder is 154 cm square find its radius​

Answer 1

area of cylinder =πr^2h

154=22/7×r^2×h

r^2=154×7/22×h

r=√7×7/h

r=7/√h

Answer 2

Answer:

$Base \: of \: a \: cylinder \: is \: circle \\ \\Area \: o f \: base \: is πr {}^{2} \\ \\ ⇒154= \frac{22}{7} = r ^{2} \\ \\ ⇒r=7 cm$
