Assuming that there is no wastage in the process, find the number of small spherical loa.made from the given sphere.4 m lono on the ground and at the same time a
Answer» volume large sphere=4/3 (pi)r^3=4/3 ×3.14×3×3×3=4×3.14×9=113.04 volume of small sphere=4/3×3.14×1×1×1=4.187 let n be no. of spheres then n×4.187=113.04n=113.04/4.187n=26.99~27

Answer»

volume large sphere=4/3 (pi)r^3=4/3 ×3.14×3×3×3=4×3.14×9=113.04

volume of small sphere=4/3×3.14×1×1×1=4.187

let n be no. of spheres then

n×4.187=113.04n=113.04/4.187n=26.99~27
