Question

how to find radii of circle whose are is 154cm

Answer 1

Answer:

π=7.00141

Step-by-step explanation:

using Formula

A=πr2

r=A/π

π=154/π

π=7.00141

Answer 2

$\tt \color{plum}{Using \: the \: Formula}$

${ \color{purple}{ Area = \pi \: r ^{2} \: }}$

$\color{royalblue}Radius = \sqrt{ \frac{A}{\pi} } = \sqrt{ \frac{154}{\pi} } = 7.00141 = 7$

${ \color{orange}{Radius = 7}}$
