Question

Base area of a regular cylinder is 154 then its radius is

Answer 1

Base area of cylinder = circle
Given, area=154cm²
therefore,

area= πr²
=>πr² = 154
=>22/7×r² = 154
=>r² = 154×7/22
=>r² = 484
=>r = √484
=>r = 22cm

Answer 2

Answer:

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