If the minimum distance between their centers is 112 cm then, find the curved surface area of a sphere with half the radius as them.

</li><li><p>9856 cm<sup>2 </sup></p>
</li><li><p>4928 cm<sup>2</sup></p>
</li><li><p>8000 cm<sup>2</sup></p>
</li></ol> <h2 id="content-id-1420689537-5"><b> Mensuration 3D Questions Solution</b></h2><p>The correct answer is <strong>option 2</strong> i.e <strong>9856 cm<sup>2</sup>.</strong></p>

<p>Let the radius of both spheres is R</p>

<p>Two spheres with equal radii are placed such that they touch each other</p>

<p>So, the minimum distance between them = 112</p>

<p>⇒ R + R = 112</p>

<p>⇒ 2R = 112</p>

<p>⇒ R = 56</p>

<p>The curved surface area of a sphere with half the radius, r = 56/2 = 28</p>

<p>C.S.A of sphere= 4π(r)<sup>2</sup></p>

<p>⇒ 4 × 22/7 × 28 × 28 = (4 × 22 × 4 × 28)</p>

<p>⇒ (16 × 22 × 28) = 9856 cm<sup>2</sup></p>
