Step-by-step explanation:

If the area of a circular card board is 154 Cm2 , then its circumference (in form of pie) is ________.

\huge {\underline {\mathfrak{ \red g \blue i\green \pink v\orange e\purple n\red \: - }}}

given−

Area =154cm^2

answer−

☞Area of the circle = πr^2

☞154 =22/7 × r^2

☞(154 ×7)/22 =r^2

☞ r = √49

☞ r = 7
