<p>If the surface area of two spheres is in the ratio 49 : 25</p>

<p>Let r and R be the radius of 1<sup>st</sup> and 2<sup>nd</sup> spheres then,</p>

<p>Surface area of sphere = πr<sup>2</sup>.</p>

<p>πr<sup>2</sup>/πR<sup>2</sup> = 49/25</p>

<p>r/R = 7/5</p>

<p>volume of sphere = 4πr<sup>3</sup>/3</p>

<p>4πr<sup>3</sup>/3 : 4πR<sup>3</sup>/3</p>

<p>7<sup>3</sup> : 5<sup>3</sup></p>
