Answer:


Area of circle = πr²


24.64 = 22/7 × r²


24.64 × 7/22 = r²


172.48/22 = r²


7.84 = r²


r = 2.8 m or cm

\mathsf{For \: \: the \: \: circle}

\mathsf\blue{Area = 24.64\: \: m \: \: or \: \: cm}

\mathsf\red{Radius = \sqrt{ \frac{Area}{\pi} }} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathfrak\red{= \sqrt{ \frac{24.64}{ \frac{22}{7} } }}

 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathfrak\red{= \sqrt{ \frac{24.64 \times 7}{22} }} \\

 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\mathfrak\red{ = \sqrt{7.84} }

 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\mathfrak\red{ = 2.8\: \: m \: \: or \: \: cm}
